Title: Spring biased slide switch

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     One or more embodiments of the present invention relate to a switch configured to switch an opened-closed state between a movable contact strip and a fixed terminal by a pivotal movement of the movable contact strip, and a method of assembly the switch. 
     2. Related Art 
     A switch configured to switch an opened-closed state between a movable contact strip and a fixed terminal in a case by operating an operating member or the like is disclosed in, for example, JP-A-2006-66125 and JP-A-11-185570. 
     In a switch disclosed in JP-A-2006-66125, a contact holder including a plurality of fixed contacts fixed in one row in the lateral direction and a plurality of movable contacts mounted in one row in the lateral direction is slidably stored in a switch case formed into a box shape. An operating portion formed on the contact holder projects from an elongated hole formed in the switch case. A knob axially supported by a switch body so as to pivot is formed with an arm, and the operating portion of the contact holder engages a depression formed at a lower end of the arm. When the knob is pivoted, the arm rotates correspondingly, and the contact holder and the movable contacts slide in the lateral direction, and the opened-closed state of the movable contacts and the fixed contacts is switched. 
     In the switch disclosed in JP-A-11-185570, two terminals are fixed to a bottom portion of a base formed into a box shape, and a movable contact plate is provided in the base. A fixed contact is formed on one of the terminals, and the other terminal and the movable contact plate are connected. An opening on an upper portion of the base is closed by an operating handle. The operating handle is provided with a rib formed on a back thereof so as to project inward of the base, and the rib is formed with a hole. The movable contact plate is formed with a square bracket-shaped strip and an extending strip and the extending strip is provided with a movable contact formed thereon. One end portion of a coil spring is inserted into a hole on the rib, and the other end portion of the coil spring is inserted into the square bracket-shaped strip. When the operating handle is operated by a seesaw movement, the coil spring is displaced in a “&lt;” shape or “&gt;” shape, so that the movable contact plate pivots and the opened-closed state of the movable contact and the fixed contact is switched. 
     SUMMARY 
     In the switch as JP-A-2006-66125, the movable contacts slide leftward and rightward in association with the contact holder, and the contacts slide with respect to the fixed contacts, so that the open-close speed of the contacts, that is, the switching speed of opening and closing the contacts depends significantly on the operating speed of the knob and the contact holder. Therefore, the contact cannot be switched quickly without depending on the operating speed of the operating member. 
     In the switch according to JP-A-11-185570, when mounting the operating handle to the base, it is required to insert both end portions of the coil spring into the square bracket-shaped strip of the movable contact plate and a rib hole on the back side of the operating handle in the base which is not seen due to the presence of the operating handle. Therefore, assembling is difficult. 
     An object of one or more embodiments of the invention is to provide a switch capable of switching contact points quickly without depending on an operating speed and configured to be easy to assemble, and a method of assembling the switch. 
     A switch according to one or more embodiments of the invention includes: a case including a bottom portion and a side wall; a fixed terminal provided on the bottom portion of the case; a supporting member provided in the case; a movable contact strip supported by the supporting member so as to be pivotable in a vertical direction above the fixed terminal; a resilient member which is provided between the side wall of the case and the movable contact strip, and which urges one end portion of the movable contact strip obliquely upward; and a pressing member provided above the resilient member, wherein the movable contact strip pivots and an opened-closed state between the movable contact strip and the fixed terminal is switched by pressing a center portion of the resilient member downward by the pressing member. 
     A assembling method of the switch according to one or more embodiments of the invention includes: providing a fixed terminal on a bottom portion of a case including the bottom portion and a side wall; supporting a movable contact strip by the supporting member so as to be pivotable in a vertical direction above the fixed terminal in the case; providing a resilient member between the side wall of the case and the movable contact strip, and urging one end portion of the movable contact strip obliquely upward by the resilient member; and providing a pressing member above the resilient member. 
     With the configurations described above, the pressing member presses a center portion of the resilient member downward, so that the movable contact strip pivots and an opened-closed state between the movable contact strip and the fixed terminal is switched. In other words, the movable contact strip does not slide with respect to the fixed terminal, but the movable contact strip pivots and comes into contact or out of contact with the fixed terminal. Therefore, the opening-closing state of the contacts between the movable contact strip and the fixed terminal can be switched quickly without depending on the operating speed for operating the pressing member. In addition, since the fixed terminal, the supporting member, the movable contact strip, the resilient member, and the pressing member are assembled in this order upward to the box-shaped case, the switch can be assembled while viewing the respective members. 
     In one or more embodiments of the invention, the switch may further include an operating member provided above the case and the pressing member so as to be operable, and the pressing member presses the center portion of the resilient member in conjunction with the operation of the operating member. 
     In one or more embodiments of the invention, in the method of assembling the switch, the operating member may be provided above the case and the pressing member. 
     In one or more embodiments of the invention, the switch may further include a cover which closes an opening opened on top of the case, the pressing member may penetrate through the cover and be held by the cover so as to be movable in the vertical direction, and be supported by the center portion of the resilient member from below, and the operating member may be held by an upper portion of the cover so as to be slidable in the lateral direction in which both end portions of the movable contact strip are arranged, and include an inclined surface which presses the pressing member downward at a time of sliding movement on a surface opposing the cover. 
     In one or more embodiments of the invention, the switch may further include a cover which closes an opening opened on top of the case, the pressing member may include a rotating shaft, penetrate through the cover and be held by the cover so as to be rotatable in a depth direction toward a bottom portion of the case, and be supported by the resilient member from below, and the operating member may be held by an upper portion of the cover so as to be slidable in a lateral direction in which both end portions of the movable contact strip are arranged, and include an inclined surface which presses and rotates the pressing member toward the resilient member downward at a time of sliding movement on a surface opposing the cover. 
     In one or more embodiments of the invention, in the switch, the pressing member and the operating member may be integrally formed, supported on the case so as to allow a rotational operation in a depth direction toward the bottom portion of the case, and press the center portion of the resilient member at the time of the rotational operation. 
     In one or more embodiments of the invention, in the switch, the fixed terminal may include: a first fixed terminal provided with a normally-opened fixed contact; a second fixed terminal provided with a normally-closed fixed contact; and a third fixed terminal arranged between the both terminals, the supporting member may be formed of a conductive material, and mounted on the third fixed terminal, and bring the third fixed terminal and the movable contact strip into conduction, the movable contact strip may cause the one end portion to be placed on the normally-opened fixed contact, and cause the other end portion to be placed on the normally-closed fixed contact, and the resilient member may urge the one end portion of the movable contact strip obliquely upward so as to cause the one end portion of the movable contact strip to be separated from the normally-opened fixed contact, and simultaneously cause the other end portion of the movable contact strip to be brought into contact with the normally-closed fixed contact. 
     In one or more embodiments of the invention, in the switch, the first fixed terminal may be provided alone in the case, the second fixed terminal, the third fixed terminal, the supporting member, the movable contact strip, the resilient member, and the pressing member may be provided in left and right pairs respectively on both sides of the first fixed terminal, when the operating member is operated in a first operating direction, one of the pressing members may press a center portion of one of the resilient members and one of the movable contact strips may pivot to switch an opened-closed state between one of the normally-closed fixed contacts and the normally-opened fixed contact, and when the operating member is operated in a second operating direction, the other pressing member may press a center portion of the other resilient member and the other movable contact strip may pivot to switch an opened-closed state between the other normally-closed fixed contact and the normally-opened fixed contact. 
     According to one or more embodiments of the invention, a switch capable of switching contact points quickly without depending on an operating speed and configured to be easy to assemble, and a method of assembling the switch are provided.

The operating member  12  is mounted on the second holding portions  10   h  of the cover  10 , so that the operating member  12  is slidably provided above the case  5  and the pressing members  11 L and  11   r . Accordingly, the switch  4   (1)  is assembled as illustrated in  FIG. 6 ,  FIG. 9  to  FIG. 11C . 
     The switch  4   (1)  assembled in a manner described above is installed sideways in the interior of the module case  1  of the power window switch module  100  so that the longitudinal direction (lateral direction in  FIGS. 4A to 4C ) and a short side direction (vertical direction in  FIGS. 4A to 4C ) of the case  5  extend perpendicularly to the pivotal shaft  1   j  of the knob  3  as illustrated in  FIGS. 4A to 4C . The switch  4   (1)  is fixed by the module case  1  and the module cover  2 . 
     The operating portion  12   a  of the operating member  12  is engaged with a depression  3   b  provided at an lower end of a lever  3   a  of the knob  3 . Therefore, the lever  3   a  is pivoted in association with the pivotal movement of the knob  3  about the shaft  1   j , to slide the operating member  12  leftward and rightward. 
     Respective lead portions  6   g  ( FIG. 6 ) of the fixed terminals  6   a  to  6   e  exposed from the case  5  project into the connector portion  2   a  as illustrated in  FIG. 3 . Therefore, by fitting harness, not illustrated, to the connector portion  2   a , a motor for opening and closing the window, not illustrated is electrically connected to the switch  4   (1) , and a route for flowing a high current to the motor is created. 
     Subsequently, the operation of the switch  4   (1)  will be described. 
     As illustrated in  FIG. 4A , when the knob  3  is in a neutral (not operated) state, the lever  3   a  is in the perpendicular posture, and the operating member  12  is at a neutral position. As illustrated in  FIG. 11A  and  FIG. 10A , the pressing members  11 L and  11   r  are pressed at upper ends thereof by inclined portions  12   e  and  12   f  of the operating member  12 , and slightly press the center portions  9   m  of the resilient members  9 L and  9   r  respectively at lower ends thereof. Accordingly, the resilient members  9 L and  9   r  are sagged and urge the end portions  8   b  of the movable contact strips  8 L and  8   r  obliquely upward where the bosses  5   b  of the both side walls  5   c  of the case  5  are present, respectively. Therefore, the end portions  8   b  of the movable contact strips  8 L and  8   r  separate from the normally-opened fixed contacts NO of the first fixed terminal  6   a , while the other end portions  8   a  thereof are in contact with the normally-closed fixed contacts NC on the second fixed terminals  6   d  and  6   e , respectively. 
     As illustrated in  FIG. 10A , since the supporting member  7   r  is normally in contact with the third fixed terminal  6   c  and the movable contact strip  8   r  respectively, the third fixed terminal  6   c  and the second fixed terminal  6   e  are in conducting state via the supporting member  7   r  and the movable contact strip  8   r . As illustrated in  FIG. 11A , since the supporting member  7 L is normally in contact with the third fixed terminal  6   b  and the movable contact strip  8 L respectively, the third fixed terminal  6   n  and the second fixed terminal  6   d  are in conducting state via the supporting member  7 L and the movable contact strip  8 L. Therefore, both current routes for normal rotation and for reverse rotation of the motor for opening and closing the window are in an opened (blocked) state, and hence no current flows to the motor, whereby the motor and the window are standstill. 
     As illustrated in  FIG. 4B , when the front end portion  3   c  of the knob  3  is pressed downward and pivots the knob  3  into an opening direction (counterclockwise in  FIG. 4B ), the lever  3   a  pivots and slides the operating member  12  in the first operating direction (rightward in  FIG. 4B ). Then, as illustrated in  FIG. 10B , an upper end of a pressing member  11   r  on one (right) side slides against the inclined portion  12   f  of the operating member  12 , and the pressing member  11   r  moves downward to cause the center portions  9   m  of the resilient member  9   r  further downward to be bent. In other words, in conjunction with the sliding operation of the operating member  12  in the first operating direction, the pressing member  11   r  presses the center portions  9   m  of the resilient member  9   r  downward. 
     As illustrated in  FIG. 100 , when the operating member  12  slides in the first operating direction by a predetermined amount and the pressing member  11   r  presses the center portion  9   m  of the resilient member  9   r  downward by a predetermined amount, the resilient member  9   r  is significantly bent and hence the end portions  8   b  of the movable contact strip  8   r  cannot be urged obliquely upward. The perpendicular portion  8   d  of the movable contact strip  8   r  is pulled downward by the resilient member  9   r , and the movable contact strip  8   r  pivots by a seesaw movement counterclockwise in  FIG. 10C  about a projection  8   e  ( FIG. 8 ) engaging the depressed portion  7   c  ( FIGS. 7A and 7B ) of the supporting member  7   r . Then, the end portion  8   a  of the movable contact strip  8   r  moves away from the normally-closed fixed contacts NC of the second fixed terminal  6   e  and the end portions  8   b  comes into contact with the normally-opened fixed contacts NO of the first fixed terminal  6   a . Therefore, when the third fixed terminal  6   c  and the first fixed terminal  6   a  are brought into a conducting state via the supporting member  7   r  and the movable contact strip  8   r , and the current route for normal rotation of the motor is brought into a closed (conducting) state, whereby a current flows to the motor and the motor rotates normally, so that the window is opened. 
     As illustrated in  FIG. 4C , when the front end portion  3   c  of the knob  3  is pulled upward and pivots the knob  3  in the closing direction (clockwise in  FIG. 4C ), the lever  3   a  pivots and slides the operating member  12  in the second operating direction (leftward in  FIG. 40 ). Then, as illustrated in  FIG. 11B , an upper end of the pressing member  11 L on the other (left) side slides against the inclined portion  12   e  of the operating member  12 , and the pressing member  11 L moves downward to cause the center portions  9   m  of the resilient member  9 L further downward to be bent. In other words, in conjunction with the sliding operation of the operating member  12  in the second operating direction, the pressing member  11 L presses the center portions  9   m  of the resilient member  9 L downward. 
     As illustrated in  FIG. 110 , when the operating member  12  slides in the second operating direction by a predetermined amount and the pressing member  11 L presses the center portion  9   m  of the resilient member  9 L downward by a predetermined amount, the resilient member  9 L is significantly bent and hence the end portions  8   b  of the movable contact strip  8 L cannot be urged obliquely upward. The perpendicular portion  8   d  of the movable contact strip  8 L is pulled downward by the resilient member  9 L, and the movable contact strip  8 L pivots by a seesaw movement clockwise in  FIG. 11C  about the projection  8   e  ( FIG. 8 ) engaging the depressed portion  7   c  ( FIGS. 7A and 7B ) of the supporting member  7 L. Then, the other end portion  8   a  of the movable contact strip  8 L moves away from the normally-closed fixed contacts NC of the second fixed terminal  6   d  and the end portions  8   b  comes into contact with the normally-opened fixed contacts NO of the first fixed terminal  6   a . Therefore, when the third fixed terminal  6   b  and the first fixed terminal  6   a  are brought into a conducting state via the supporting member  7 L and the movable contact strip  8 L, and the current route for reverse rotation of the motor is brought into a closed state, whereby a current flows to the motor and the motor rotates reversely, so that the window is closed. 
     When the operation on the knob  3  is released, the knob  3  and the operating member  12  are restored to the neutral state illustrated in  FIGS. 4A, 10A and 11A  by a restoration mechanism, which is not illustrated. Therefore, the pressing members  11 L and  11   r  are separated from the inclined surfaces  12   e  and  12   f  of the operating member  12 , respectively, and are pushed upward by a resilient restoring force of the resilient members  9 L and  9   r , and upper ends of the pressing members  11 L and  11   r  engage the engaging grooves  12   c  and  12   d . The resilient members  9 L and  9   r  urge the end portions  8   b  of the movable contact strips  8 L and  8   r  obliquely upward, respectively, so that the end portions  8   b  of the movable contact strips  8 L and  8   r  separate from the normally-opened fixed contacts NO of the first fixed terminal  6   a , while the other end portions  8   a  thereof are in contact with the normally-closed fixed contacts NC on the second fixed terminals  6   d  and  6   e , respectively. Therefore, the third fixed terminals  6   b  and  6   c  are brought into a non-conducting state with respect to the first fixed terminal  6   a , and are brought into a conducting state with the second fixed terminals  6   d  and  6   e  via the supporting members  7 L and  7   r  and the movable contact strips  8 L and  8   r , respectively. Therefore, both current routes for normal rotation and for reverse rotation of the motor are in an opened state, and hence no current flows to the motor, whereby the motor and the window are standstill. 
     As another example, the following configuration is also applicable. Irrespective of the presence or absence of the restoration mechanism, which is not illustrated, if the operation on the knob  3  is released, the pressing member  11 L ( 11   r ) which is pushed upward by a resilient restoration force of the resilient member  9 L ( 9   r ) moves along the inclined surface  12   e  ( 12   f ) of the operating member  12 . Accordingly, the operating member  12  moves leftward (rightward), and the knob  3  is restored to the neutral state. 
     According to the switch  4   (1)  of the first embodiment, in conjunction with the sliding operation of the operating member  12  by the knob  3 , the pressing members  11 L and  11   r  are pressed downward by the inclined surfaces  12   e  and  12   f  of the operating member  12 . Then, the center portions  9   m  of the resilient members  9 L and  9   r  are pressed by the pressing members  11 L and  11   r  to pivot the movable contact strips  8 L and  8   r , and the opened-closed state of the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  is switched. In other words, the movable contact strips  8 L and  8   r  do not slide in the lateral direction in association with the operating member  12  against the fixed terminals  6   a  to  6   e , but the movable contact strips  8 L and  8   r  make a seesaw movement by the actions of the resilient members  9 L and  9   r  and come into contact with or away from the fixed terminals  6   a  to  6   e . Therefore, the opening-closing state of the contact between the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  can be switched quickly without depending on the operating speed of the knob  3  and the operating member  12 . 
     In the first embodiment, the fixed terminals  6   a  to  6   e , the supporting members  7 L and  7   r , the movable contact strips  8 L and  8   r , and the resilient members  9 L and  9   r  are assembled upward in sequence in the interior of the box-shaped case  5 . Then, the opening  5   a  of the case  5  is covered with the cover  10 , and from the upper portion of the cover  10 , the pressing members  111 , and  11   r  and the operating member  12  are assembled in sequence. Therefore, assembly is easily achieved while viewing these members. 
     In the first embodiment described above, when the knob  3  and the operating member  12  are in neutral, the other end portions  8   a  of the movable contact strips  8 L and  8   r  are brought into contact with normally-closed fixed contacts NC of the second fixed terminals  6   d  and  6   e  respectively while moving the end portion  8   b  thereof away from the normally-opened fixed contacts NO of the first fixed terminal  6   a  by a resilient urging force of the resilient members  9 L and  9   r . Therefore, the second fixed terminals  6   d  and be and the third fixed terminals  6   b  and  6   c  can be brought in conduction with each other via the movable contact strips  8 L and  8   r  and the supporting members  7 L and  7   r , respectively. 
     In the first embodiment described above, by sliding the operating member  12  in the first operating direction via the knob  3 , the movable contact strip  8   r  pivots to bring the end portion  8   b  of the movable contact strip  8   r  into contact with the normally-opened fixed contacts NO of the first fixed terminal  6   a  and, simultaneously, the other end portion  8   a  moves away from the normally-closed fixed contacts NC of the second fixed terminal  6   e . Therefore, the first fixed terminal  6   a  and the third fixed terminal  6   c  can be brought in conduction with each other via the movable contact strip  8   r  and the supporting member  7   r , respectively. 
     In the first embodiment described above, by sliding the operating member  12  in the second operating direction via the knob  3 , the movable contact strip  8 L pivots to bring the end portion  8   b  of the movable contact strip  8 L into contact with the normally-opened fixed contacts NO of the first fixed terminal  6   a  and, simultaneously, the other end portion  8   a  moves away from the normally-closed fixed contacts NC of the second fixed terminal  6   d . Therefore, the first fixed terminal  6   a  and the third fixed terminal  6   b  can be brought in conduction with each other via the movable contact strip  8 L and the supporting member  7 L, respectively. 
       FIG. 12  to  FIG. 16C  are drawings illustrating a switch  4   (2)  of a second embodiment. 
     Specifically,  FIG. 12  is an exploded perspective view of the switch  4   (2) .  FIG. 13  is an assembly drawing of the switch  4   (2) .  FIG. 14  is a cross-sectional view taken along the line E-E in  FIG. 13 .  FIGS. 15A to 15C  are cross-sectional views taken along the line F-F in  FIG. 13  illustrating an operation of the switch  4   (2) .  FIGS. 16A to 16C  are cross-sectional views taken along the line G-G in  FIG. 13  illustrating the operation of the switch  4   (2) . 
     As illustrated in  FIG. 12 , a pair of the pressing members  14 L and  14   r  provided on the switch  4   (2)  include projections  14   b  formed on an upper surfaces at centers, rotating shafts  14   j  formed at end portions, and arm portions  14   a  extending sidewards from the rotating shaft  14   j . A cover  13  is provided with a pair of first holding portions  13   a  configured to hold the pressing members  14 L and  14   r  so as to be movable in the depth direction toward the bottom portion  5   t  of the case  5 . The first holding portions  13   a  each includes a hole  13   h  penetrating through the cover  13  in the vertical direction, and a bearing portion  13   j  configured to support the rotating shaft  14   j  as illustrated in  FIGS. 15A to 15C  and  FIGS. 16A to 16C . 
     The cover  13  is mounted on the case  5  so as to close the opening  5   a  of the case  5  (see  FIG. 13  to  FIG. 16C ). The pressing members  14 L and  14   r  are mounted on the respective first holding portions  13   a  of the cover  13  from above. Accordingly, as illustrated in  FIGS. 15A to 15C  and  FIGS. 16A to 16C , the pressing members  14 L and  14   r  penetrate through the cover  13 , and are held by the cover  13  so as to be rotatable about the rotating shaft  14   j . The pressing members  14 L and  14   r  are supported at lower ends of the arm portions  14   a  by center portions  9   m  of the resilient members  9 L and  9   r.    
     The projections  12   b  formed on side surfaces of the operating member  12  are inserted into the second holding portions  10   b  formed on an upper portion of the cover  13  in parallel to the longitudinal direction of the cover  13  and the operating member  12  illustrated in  FIG. 12 . Accordingly, as illustrated in  FIG. 13  to  FIG. 16C , the operating member  12  is held on an upper portion of the cover  13  so as to be slidable in the lateral direction above the case  5  and the pressing member  141 , and  14   r.    
     The lower surface of the operating member  12  opposing the cover  13  is provided with engaging grooves  12   c ′ and  12   d ′ that allows engagement of projections  14   b  of the pressing member  14 L and  14   r . The engaging grooves  12   c ′ and  12   d ′ are provided with inclined surfaces  12   e ″ and  12   f ′ formed so as to be lowered as they go toward the operating portion  12   a  side. 
     When assembling the switch  4   (2)  having the structure as described above, the fixed terminals  6   a  to  6   e , the supporting members  7 L and  7   r , the movable contact strips  8 L and  8   r , and the resilient members  9 L and  9   r  are assembled upward in sequence in the interior of the case  5 . Then, the cover  13  is mounted on the case  5 , the opening  5   a  is closed by the cover  13 , the pressing members  14 L and  14   r  are mounted on the first holding portions  13   a  of the cover  13 , and the pressing members  14 L and  14   r  are provided above the resilient members  9 L and  9   r . The operating member  12  is mounted on the second holding portions  10   b  of the cover  13 , so that the operating member  12  is slidably provided above the case  5  and the pressing members  14 L and  14   r . Accordingly, the switch  4   (2)  is assembled as illustrated in  FIG. 13  to  FIG. 16C . 
     The switch  4   (2)  assembled as described above is installed sideways in the module case  1  as illustrated in  FIGS. 4A to 4C . In this state of installation, the operating portion  12   a  of the operating member  12  engages the depression  3   b  of the lever  3   a  of the knob  3 . 
     Subsequently, an operation of the switch  4   (2)  will be described. 
     As illustrated in  FIG. 4A , when the knob  3  is in a neutral state, the operating member  12  is at a neutral position. As illustrated in  FIG. 16A  and  FIG. 15A , the pressing members  14 L and  14   r  are pressed at projections  14   b  thereof by the inclined portions  15   e  and  15   f  of the operating member  15 , and slightly press the center portions  9   m  of the resilient members  9 L and  9   r  respectively at distal ends of the arm portions  14   a . Accordingly, the resilient members  9 L and  9   r  are slightly sagged and urge the end portions  8   b  of the movable contact strips  8 L and  8   r  obliquely upward where the bosses  5   b  of the both side walls  5   c  of the case  5  are present, respectively. Therefore, the end portions  8   b  of the movable contact strips  8 L and  8   r  separate from the normally-opened fixed contacts NO of the first fixed terminal  6   a , while the other end portions  8   a  of the movable contact strips  8 L and  8   r  are in contact with the normally-closed fixed contacts NC on the second fixed terminals  6   d  and  6   e , respectively. 
     Since the supporting members  7 L and  7   r  are normally in contact with the third fixed terminals  6   b  and  6   c  and the movable contact strips  8 L and  8   r , the third fixed terminals  6   b  and  6   c  and the second fixed terminals  6   c   1  and  6   e  are in conducting state via the supporting members  7 L and  7   r  and the movable contact strips  8 L and  8   r  respectively. Therefore, both current routes for normal rotation and for reverse rotation of the motor for opening and closing the window are in an opened state, and hence no current flows to the motor, whereby the motor and the window are standstill. 
     As illustrated in  FIG. 4B , when the knob  3  is pivoted in the opening direction, the lever  3   a  pivots and the operating member  12  is slid in the first operating direction. As illustrated in  FIG. 15B , the projection  14   b  of the pressing member  14   r  and the inclined surface  12   f ′ of the operating member  12  slide, while the projection  14   b  is pressed by the inclined surface  12   f ′, so that the pressing member  14   r  rotates clockwise in  FIG. 15B  about the rotating shaft  14   j . Accordingly, the arm portion  14   a  of the pressing member  14   r  pivots downward, and makes the center portion  9   m  of the resilient member  9   r  sagged further downward and bent. In other words, in conjunction with the sliding operation of the operating member  12  in the first operating direction, the pressing member  14   r  presses the center portions  9   m  of the resilient member  9   r  downward. 
     As illustrated in  FIG. 15C , when the operating member  12  slides in the first operating direction by a predetermined amount, the pressing member  14   r  rotates by a predetermined angle and presses the center portion  9   m  of the resilient member  9   r  downward with the arm portion  14   a  by a predetermined amount, the resilient member  9   r  is significantly bent and hence the end portions  8   b  of the movable contact strip  8   r  cannot be urged obliquely upward. The perpendicular portion  8   d  of the movable contact strip  8   r  is pulled downward by the resilient member  9   r , and the movable contact strip  8   r  pivots by a seesaw movement counterclockwise in  FIG. 15C  about the projection  8   e  ( FIG. 8 ). Then, the other end portion  8   a  of the movable contact strip  8   r  moves away from the normally-closed fixed contacts NC of the second fixed terminal  6   e  and the end portions  8   b  comes into contact with the normally-opened fixed contacts NO of the first fixed terminal  6   a . Therefore, when the third fixed terminal  6   c  and the first fixed terminal  6   a  are brought into a conducting state via the supporting member  7   r  and the movable contact strip  8   r , and the current route for normal rotation of the motor is brought into a closed state, whereby a current flows to the motor and the motor rotates normally, so that the window is opened. 
     As illustrated in  FIG. 4C , when the front end portion  3   c  of the knob  3  is pulled upward and the knob  3  is pivoted in the closing direction, the lever  3   a  pivots and slides the operating member  12  in the second operating direction. As illustrated in  FIG. 16B , the projection  14   b  of the pressing member  14 L and the inclined surface  12   e ′ of the operating member  12  slide, while the projection  14   b  is pressed by the inclined surface  12   e ′, so that the pressing member  14 L rotates counterclockwise in  FIG. 16B  about the rotating shaft  14   j . Accordingly, the arm portion  14   a  of the pressing member  141  pivots downward, and make the center portion  9   m  of the resilient member  9 L sagged further downward and bent. In other words, in conjunction with the sliding operation of the operating member  12  in the second operating direction, the pressing member  14 L presses the center portions  9   m  of the resilient member  9 L downward. 
     As illustrated in  FIG. 16C , when the operating member  12  slides in the second operating direction by a predetermined amount, the pressing member  141  rotates by a predetermined angle and presses the center portion  9   m  of the resilient member  9 L downward with the arm portion  14   a  by a predetermined amount, the resilient member  9 L is significantly bent and hence the end portions  8   b  of the movable contact strip  8 L cannot be urged obliquely upward. The perpendicular portion  8   d  of the movable contact strip  8 L is pulled downward by the resilient member  9 L, and the movable contact strip  8 L pivots by a seesaw movement clockwise in  FIG. 16C  about the projection  8   e  ( FIG. 8 ). Then, the other end portion  8   a  of the movable contact strip  8 L moves away from the normally-closed fixed contacts NC of the second fixed terminal  6   d  and the end portions  8   b  comes into contact with the normally-opened fixed contacts NO of the first fixed terminal  6   a . Therefore, when the third fixed terminal  6   b  and the first fixed terminal  6   a  are brought into a conducting state via the supporting member  7 L and the movable contact strip  8 L, and the current route for reverse rotation of the motor is brought into a closed state, whereby a current flows to the motor and the motor rotates reversely, so that the window is closed. 
     When the operation on the knob  3  is released, the knob  3  and the operating member  12  are restored to neutral state illustrated in  FIGS. 4A, 15A and 16A  by the restoration mechanism, which is not illustrated. Therefore, the projections  14   b  of the pressing members  14 L and  14   r  are separated from the inclined surfaces  12   e ′ and  12   f ′ of the operating member  12 , respectively, and the arm portions  14   a  are pushed upward by a resilient restoring force of the resilient members  9 L and  9   r , and the projections  14   b  engage the engaging grooves  12   c ′ and  12   d ′. The resilient members  9 L and  9   r  urge the end portions  8   b  of the movable contact strips  8 L and  8   r  obliquely upward, respectively, so that the end portions  8   b  of the movable contact strips  81 , and  8   r  separate from the normally-opened fixed contacts NO of the first fixed terminal  6   a , while the other end portions  8   a  thereof are in contact with the normally-closed fixed contacts NC on the second fixed terminals  6   d  and  6   e , respectively. Therefore, the third fixed terminals  6   b  and  6   c  are brought into a non-conducting state with respect to the first fixed terminal  6   a , and are brought into a conducting state with respect to the second fixed terminals  6   d  and Be via the supporting members  7 L and  7   r  and the movable contact strips  8 L and  8   r . Therefore, both current routes for normal rotation and for reverse rotation of the motor are in an opened state, and hence no current flows to the motor, whereby the motor and the window are standstill. 
     According to the switch  4   (2)  of the second embodiment described above, in conjunction with the sliding operation of the operating member  12  by the knob  3 , the projections  14   b  of the pressing members  14 L and  14   r  are pressed downward by the inclined surfaces  12   e ′ and  12   f ′ of the operating member  12  to rotate the pressing member  14 L and  14   r  about the rotating shafts  14   j . Then, the center portions  9   m  of the resilient members  9 L and  9   r  are pressed by the arm portions  14   a  of the pressing members  14 L and  14   r  to pivot the movable contact strips  8 L and  8   r  by a seesaw movement, and the opened-closed state of the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  is switched. Therefore, the opening-closing state of the contact between the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  can be switched quickly without depending on the operating speed of the knob  3  and the operating member  12 . 
     In the second embodiment described above, the fixed terminals  6   a  to  6   e , the supporting members  7 L and  7   r , the movable contact strips  8 L and  8   r , and the resilient members  9 L and  9   r  are assembled upward in sequence in the interior of the case  5 . Then, the opening  5   a  of the case  5  is covered with the cover  13 , and from the upper portion of the cover  13 , the pressing member  14 L and  14   r  and the operating member  12  are assembled in sequence. Therefore, assembly is easily achieved while viewing these members. 
     Furthermore, in the second embodiment described above, the amount of the sliding movement of the operating member  12  and the amount of the downward movement of the distal end sides of the arm portions  14   a  of the pressing member  14 L and  14   r  may be changed by adjusting the lengths from the rotating shafts  14   j  of the pressing member  14 L and  14   r  to the distal end portions of the arm portions  14 . Therefore, in comparison with the structure of the first embodiment described above, the amount of sliding movement may be reduced by reducing the sizes of the inclined surfaces  12   e ′ and  12   f ′ and the engaging grooves  12   c ′ and  12   d ′ of the operating member  12 , so that a reduction in frictional force between the operating member  12  and the pressing member  14 L and  14   r , and a reduction in size of the switch  4   (2)  with respect to the operating direction of the operating member  12  are achieved. 
     In the invention, various embodiments may be employed other than those described thus far. For example, in the above-described embodiments, examples in which the covers  10  and  13 , a pair of pressing members  11 L,  11   r ,  14 L, and  14   r , and the operating member  12  are provided above a pair of resilient members  9 L and  9   r  have been described. However, the invention is not limited thereto. In addition to this, for example, as a switch  4   (3)  of a third embodiment illustrated in  FIG. 17 , a rotary operating member  15  including a pressing member, an operating member, and a cover formed integrally may be provided above the resilient members  9 L and  9   r.    
     The rotary operating member  15  includes a rotating shaft  15   j  provided at a center, an operating portion  15   a  provided above the rotating shaft  15   j , and a pair of left and right pressing portions  15 L and  15   r  provided on both sides of the rotating shaft  15   j . The rotating shaft  15   j  is supported by a bearing hole  5   z  formed on the side walls of the case  5 , so that the rotary operating member  15  is supported on the case  5  so as to be rotatable in the depth direction of the case  5 , whereby the opening  5   a  is closed. A pair of the pressing portions  15 L and  15   r  are supported by center portions  9   m  of the resilient members  9 L and  9   r  from below. The operating portion  15   a  engages the depression  3   b  of the lever  3   a  of the knob  3  illustrated in  FIGS. 4A to 4C . 
     By pivoting the knob  3 , the lever  3   a  rotates the rotary operating member  15  about the rotating shaft  15   j  via the operating portion  15   a  clockwise or counterclockwise in  FIG. 17 . Accordingly, the center portions  9   m  of the resilient members  9 L and  9   r  are pressed by the pressing portions  15 L and  15   r  to pivot the movable contact strips  8 L and  8   r , and the opened-closed state of the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  is switched. 
     According to the switch  4   (3)  of the third embodiment described above, the opening-closing state between the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  can be switched quickly without depending on the operating speed of the knob  3  and the rotary operating member  15 . What is essential is only that the fixed terminals  6   a  to  6   e , the supporting members  7 L and  7   r , the movable contact strips  8 L and  8   r , and the resilient members  9 L and  9   r  are installed in the case  5  and the rotary operating member  15  is mounted in the case  5 . Therefore, assembly of the switch  4   (3)  is facilitated. In addition, since the pressing member, the operating member, and the cover are integrally formed, the number of components is reduced, so that management of the components is also facilitated. 
     Like a switch  4   (4)  of a fourth embodiment illustrated in  FIG. 18 , a single pressing member  16  having a pair of left and right pressing portions  16 L and  16   r  may be provided between the resilient members  9 L and  9   r  and the operating member  12 . The pressing member  16  is fitted into the hole portion  17   h  formed in the cover  17  that closes the opening  5   a  of the case  5 . What is to be done is just to mount the cover  17  and the pressing member  16  on the case  5  and then mount the operating member  12  on the cover  17 . 
     When the operating member  12  is slid in the lateral direction, the inclined surfaces  12   e  and  12   f  slide against upper ends of the pressing portions  16 L and  16   r , so that the pressing member  16  is inclined. Accordingly, the center portions  9   m  of the resilient members  9 L and  9   r  are pressed downward by lower ends of the pressing portions  16 L and  16   r , whereby the movable contact strips  8 L and  8   r  pivot and the opened-closed state between the movable contact strips  8 L and  8   r  and the fixed terminals  6   a  to  6   e  is switched. 
     In the embodiments described above, examples in which the resilient members  9 L and  9   r  formed of a tensile coil spring are used has been described. However, the invention is not limited thereto and, for example, other resilient members such as leaf spring may be employed. 
     Furthermore, in the embodiments described above, an example in which the invention is applied to the switch  4  for the power window switch module  100  configured to manually open and close the windows of other seats other than the driver&#39;s seat of an automotive vehicle has been exemplified. However, the invention may be applied to switches other than those described above. The number of the components used is not limited to the embodiments described above, and may be selected as needed according to the function of the switch. 
     While the invention has been described with reference to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the invention should be limited by the attached claims.
