Abstract:
The present invention is for a bi-stable battery switch incorporated preferably for internal use into a remotely switchable storage battery, or, in the alternative, for external use with a battery. A bifurcated contact assembly incorporating dual bus bars is pulse actuated by a solenoid and cam arrangement to engage or disengage across opposing contacts. When engaging the contacts and when associated with high inductive loads, the first bus bar to advance initiates contact and assumes the arcing load, while the second bus bar to advance assumes the current load. When breaking contact and when associated with high inductive loads, the first bus bar to retreat breaks the current load and the second bus bar to retreat breaks the arcing load. Thus, the loads are shared to increase the durability and length of service of the switch.

     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is for a battery switch, and more particularly, pertains to a bi-stable battery switch incorporated preferably for internal use into a remotely switchable storage battery, or, in the alternative, for external use with a battery. 
     2. Description of the Prior Art 
     Remotely switchable storage batteries, such as for use in, but not limited to, an automobile, have been offered for use as an anti-theft deterrent. A switch is contained in a battery and is operated remotely by a small hand-held remote transmitting device. An individual merely activates the remote transmitting device whereby a receiver located in the battery case is activated to trigger the disconnection of the battery circuit internally within the battery case, thereby removing available battery power to the circuits residing in the automobile such as, for example, and which may be highly inductive loads, ignition modules, starters, generators, alternators, fans and the like. Such disconnection electrically disables the automobile, or other vehicle in which the remotely switchable storage battery is installed. Often, operators of the vehicle would decide to remotely shut down and disable the vehicle with the vehicle still running as an alternative to first turning off the vehicle. Using this method, high inductive loads are still operative at the instant of remote electrical disablement. In the presence of the high inductive loads during remote shutdown, prior art switching methods, particularly with respect to the electrical switching contacts, caused excessive arcing across the switching contacts during shutdown. Excessive arcing across breaking or making electrical contacts is an undesirable trait present when breaking or making an inductive load and often causes premature degradation of the surfaces of the electrical contacts, thereby causing contact or switch failure. Remote reconnection and enabling of the remotely switchable storage battery provides an imposition of inductive loads across the switch contacts, also causing undesirable contact arcing leading to premature failure of the contacts. 
     Clearly what is needed is a switching device which overcomes the flaws and deficiencies of the prior art. 
     SUMMARY OF THE INVENTION 
     The general purpose of the present invention is a bi-stable battery switch for incorporation into or about a remotely switchable storage battery. The bi-stable battery switch in general is a double bar bus switch in which a solenoid pulses a cam which in turn actuates or de-actuates two parallel circuit spring loaded positionable bus bars comprising a bifurcated contact assembly to either break or make an electrical connection across adjacent and aligned stationary and wide V-shaped contacts located on switch terminals. Each of the positionable bus bars is cam operated or influenced and is in the form of a movable bar having two contacts located thereupon, each contact having an arced surface. During the making of an electrical contact to connect the battery to the electrical system of an automobile, the direct influence of a cam is eliminated to allow spring forces to urge the two spring loaded positionable bus bars of the bifurcated contact assembly into near simultaneous dual contact with and across the wide stationary V-shaped contacts of the switch terminals. Although both positionable bus bars are springingly and simultaneously urged toward and into intimate dual contact with the stationary and wide contacts located on the switch terminals, one positionable bus bar precedes, in a very short time span, the adjoining positionable bus bar and picks up the arcing load in contacting the wide contacts of the switch terminals only to be closely followed by the remaining positionable bus bar which in contacting the wide contacts of the switch terminals picks up the current load. 
     According to one or more embodiments of the present invention there is provided a bi-stable battery switch for use with and for incorporation into internal use with a remotely switchable storage battery, or, in the alternative, for external use with a battery. The bi-stable battery switch is built about and within a substantially rectangular enclosure having a top and a bottom to which components align and secure. Located in the rectangular enclosure is a vertically aligned cam and associated members which are actuated by a cam driver arm connected to the solenoid core. Adjacent to the vertically aligned cam is a bifurcated contact assembly having two spring loaded positionable bus bars which are aligned to and actuated by the vertically aligned cam. A large switch terminal and a small switch terminal, each having wide V-shaped contacts which are sized to contact the arc-shaped contacts on both positionable bus bars, align to the bifurcated contact assembly to either make or break contacts thereupon. 
     One significant aspect and feature of the present invention is a bi-stable battery switch which exhibits a long life. 
     Another significant aspect and feature of the present invention is a bi-stable battery switch having a bifurcated contact assembly having an upper and a lower bus bar. 
     Still another significant aspect and feature of the present invention is a bi-stable battery switch where a cam arrangement is used in pulse fashion to cause advancing or retarding of a bifurcated contact assembly. 
     Yet another significant aspect and feature of the present invention is the incorporation of upper and lower bus bars whereby inductive loads are distributed along both the upper and lower bus bars. In making of the contacts, the first to accept an inductive load accepts an arcing load while the second to accept an inductive load accepts a current load; while in breaking of the contacts, the first to shed an inductive load sheds a current load and the second to shed an inductive load sheds an arcing load. 
     Having thus described an embodiment of the present invention and specified significant aspects and features thereof, it is the principal object of the present invention to provide a bi-stable battery switch.

     FIG. 2 illustrates an exploded isometric view of the bi-stable battery switch  10 , where all numerals previously mentioned correspond to those elements previously described. With reference to FIG.  2  and with implied reference to other figures showing the invention, components of the bi-stable battery switch  10  and their relationship is now described. The small switch terminal  18 , also shown in FIG. 3, includes a horizontally oriented planar structure  18   a , a vertically oriented planar structure  18   b  extending downwardly from horizontally oriented planar structure  18   a , and a planar contact mounting pad  18   c  extending at a right angle and inwardly from the vertically oriented planar structure  18   b . A dual and continuous contact  26  having juxtaposed wide V-shaped contact surface arrangements (FIG. 3) secures to one side of the contact mounting pad  18   c . Correspondingly, the large switch terminal  20 , also shown in FIG. 4, includes a horizontally oriented planar structure  20   a , a small vertically oriented planar structure  20   b  extending upwardly from the horizontally oriented planar structure  20   a , a horizontally oriented planar structure  20   c  extending horizontally from the vertically oriented planar structure  20   b , a U-shaped structure  20   d  extending downwardly from the horizontally oriented planar structure  20   c , a vertically oriented planar structure  20   e  extending downwardly from the U-shaped structure  20   d , and a planar contact mounting pad  20   f  (FIG. 4) extending at a right angle and inwardly from the vertically oriented planar structure  20   e . A dual and continuous contact  28  having juxtaposed wide V-shaped contact surface arrangements (FIG. 4) secures to one side of the contact mounting pad  20   f.    
     Located in close proximity and alignment to the contacts  26  and  28  is a bifurcated contact assembly  30  having identical but mutually inverted and opposing spring loaded positionable upper and lower bus bars  32  and  34  located in close proximity and alignment for contacting of the contacts  26  and  28 . As shown in FIG. 5, the upper bus bar  32 , and thus also the identical lower bus bar  34 , includes opposing arc-shaped contacts  36  and  38 , a cam surface  40  disposed vertically between the opposing arc-shaped contacts  36  and  38 , and, a guide bar  42  located on a planar surface  44  and at a right angle to the cam surface  40 . Upper and lower channel-shaped contact guides  46  and  48  interface between the upper and lower bus bars  32  and  34  and the enclosure top  14  and the enclosure bottom  12 , respectively, as later described in detail. A rectangular spring holder  50  serves as a base for a plurality of springs  52   a - 52   n  whose purpose is to provide inwardly directed pressure to position the upper and lower bus bars  32  and  34  into electrical contact with and across the contacts  26  and  28  when allowed by the position of a cam  54 . 
     The enclosure bottom  12  and the enclosure top  14  together form an enclosure to which components align and secure about and within, including, but not limited to, the bifurcated contact assembly  30 , the rectangular spring holder  50  and springs  52   a - 52   n , the upper and lower contact guides  46  and  48 , the small switch terminal  18 , the large switch terminal  20 , the solenoid  16 , a solenoid operated cam driver arm  56 , and the cam  54  and associated members. The cam  54  and the associated members including a cam pivot pin  58 , a cam driver  60 , a carrier driver  62 , springs  64   a  and  64   b , and balls  66   a  and  66   b  are located and/or secured between the enclosure bottom  12  and the enclosure top  14  each of which includes suitable geometrical configurations to accommodate the cam  54  and associated cam related members as well as other elements of the invention. 
     The enclosure bottom  12  (FIG. 6) includes a substantially planar bottom  68 , a vertically aligned end  70 , an open end opposing the end  70 , and a vertically aligned left side  72  and right side  74 . Cutouts  72   a  and  74   a  in the left and right sides  72  and  74  accommodate and support the vertically oriented planar structure  20   e  and the vertically oriented planar structure  18   b  of the small switch terminal  18  and the large switch terminal  20 , respectively, which in part anchor the large switch terminal  20  and the small switch terminal  18 . The bottom  68  includes geometrically configured recessed or other regions on its upper surface including a channeled recess  76  which intersects a circular recess  78 , an elongated recess  80  located in the channeled recess  76 , a circular recess  82  located central to the circular recess  78 , an upwardly extending solenoid core stop  84 , and a rectangular recess  86  for accommodation of the lower contact guide  48 . Also included are rectangular recesses  88  and  90  for the accommodation of the combined lower ends of contact  28 /contact mounting pad  20   f  and the combined lower ends of contact  26 /contact mounting pad  18   c , respectively, which can in part anchor the large switch terminal  20  and the small switch terminal  18 . Geometrically configured capturing slots  92  and  94  are located on the underside of the bottom  68  for positive mating with the tabs  96  and  98  of the framework  100  of the solenoid  16 . 
     The enclosure top  14  (shown inverted in FIG. 7) also includes geometrically configured capturing slots  102  and  104  located on the top surface for positive mating with tabs  95  and  97  of the framework  100  of the solenoid  16 . Also included are recesses  106  and  108  for accommodation of portions of the vertically oriented planar structures  20   e  and  18   b  of the large switch terminal  20  and the small switch terminal  18 . The enclosure top  14  includes geometrically configured recessed or other regions on its lower surface, some of which are similar to those found on the enclosure bottom  12 , including a rectangular recess  110  for accommodation of the upper contact guide  46 , rectangular recesses  112  and  114  for the accommodation of the combined upper ends of contact  28 /contact mounting pad  20   f  and the combined lower ends of contact  26 /contact mounting pad  18   c , respectively, which can in part anchor the large switch terminal  20  and the small switch terminal  18 . In addition, a circular recess  116  in opposition to circular recess  82  of the enclosure bottom  12  is located on the undersurface of the enclosure top  14 . Together, circular recesses  116  and  82  serve as upper and lower mounts for the cam pivot pin  58 . A series of detent grooves  118   a - 118   n  having ramped depth are located concentric to the circular recess  116 . 
     The cam  54 , and other associated components, are located along and about the vertically oriented cam pivot pin  58 . The cam driver  60  (shown inverted in FIG. 8) is substantially disk-shaped and includes a centrally located hole  120  extending therethrough, a plurality of ratchet teeth  122   a - 122   n  on the upper side, a recessed portion  124  on the lower side, and an engagement hole  126  extending vertically through the cam driver  60  in the area of the recessed portion  124 . The cam driver  60  aligns over and about and is allowed to be actuated about the cam pivot pin  58 . The cam driver  60  freely aligns in the circular recess  78  in the bottom  68  of the enclosure bottom  12 . Aligned in the channeled recess  76  of the enclosure bottom  12  is the cam driver arm  56  which includes a cam driver pin  57  extending vertically through and extending both above and below the cam driver arm  56 . The lower end of the cam driver pin  57  is freely accommodated by the elongated recess  80  in the bottom  68  of the enclosure bottom  12  and the upper end of the cam driver pin  57  rotatingly engages the engagement hole  126 . Hole  126  is slightly larger than the diameter of the cam driver pin  57  to allow for non-bonding engagement of the cam driver pin  57  with the hole  126 , as hole  126  moves along an arcuate path during rotation about the cam pivot pin  58 . The solenoid  16 , which includes a solenoid core  128 , a pole face  130 , a spacer  132 , a bobbin  134 , a guide pin  136 , a core stud assembly  138 , a spring  139 , and the framework  100 , actuates the cam driver arm  56  to subsequently rotate the cam driver  60  in a counterclockwise fashion. Also aligned freely over and about the cam pivot pin  58  as well as aligned in intimate contact with the cam driver arm  56  is the carrier driver  62 . 
     The cam driver  62  (also shown in FIG. 9) includes vertically aligned cylindrical spring mounts  140  and  142  extending from its top surface for mounting of the lower ends of the springs  64   a  and  64   b  and also includes a plurality of ratchet teeth  144   a - 144   n  located along and extending downwardly from the bottom surface. Ratchet teeth  144   a - 144   n  accommodatingly correspond to and intimately contact and positively engage (in one direction) the ratchet teeth  122   a - 122   n  on the upper surface of the cam driver  60 . Positive engagement of ratchet teeth  122   a - 122   n  and ratchet teeth  144   a - 144   n  occurs in a counterclockwise manner when the cam driver arm  56  is actuated inwardly and to the right by the solenoid  16 . Subsequent to this action and when power is interrupted to the solenoid  16 , the recoiling action of the solenoid returns the cam driver arm  56  and thus the cam driver  60 , by virtue of the slipping of the ratchet teeth  122   a - 122   n  with ratchet teeth  144   a - 144   n , in the reverse direction, to the rest or non-actuated position after positioning of the carrier driver  62 . Such cycling of the solenoid  16  provides for 45° counterclockwise rotational repositioning of the carrier driver  62  and of the attached cam  54 . Such repositioning provides for repositioning of the bifurcated contact assembly  30  to either make or break electrical contact across the contacts  26  and  28 . 
     The cam  54 , shown inverted in FIG. 10, includes a plurality of vertically aligned cam lobes  146   a - 146   n  which align in parallel and concentric fashion to a centrally located annular centering extension  148  on the underside of the cam  54  and which also align in parallel and concentric fashion to a co-located pivot hole  150  extending through the body of the cam  54  and extending through the annular centering extension  148 . Structure of the cam  54  and the relationship to the underlying structures is found in the description of FIG.  10 . Also visible are the upper regions of spring bores  152  and  154  to which balls  66   a  and  66   b  align, respectively. The balls  66   a  and  66   b  interface between the cam  54  and the detent grooves  118   a - 118   n  of the enclosure top  14  (FIG. 7) to provide detented positional fixation for proper alignment of the cam  54  and to ensure that the cam  54  and the carrier driver  62  are not allowed to rotatingly regress and that they are held in their advanced position as the cam driver  60  returns to the unactuated position upon release of power application to the solenoid  16 . 
     FIG. 3 illustrates an isometric view of the small switch terminal  18 , where all numerals mentioned previously correspond to those elements previously described. Illustrated in particular is dual and continuous contact  26  having juxtaposed wide V-shaped contact surfaces including surfaces  26   a  and  26   b  which are angled and which mutually intersect and surfaces  26   c  and  26   d  which are angled and which mutually intersect. The surfaces  26   a  and  26   b  provide for multi-point contact with the arc-shaped contact  38  of the upper bus bar  32  and the surfaces  26   c  and  26   d  provide for multi-point contact with the arc-shaped contact  38  of the lower bus bar  34 . 
     FIG. 4 illustrates an isometric view of the large switch terminal  20  where all numerals mentioned previously correspond to those elements previously described. Illustrated in particular is dual and continuous contact  28  having juxtaposed wide V-shaped contact surfaces including surfaces  28   a  and  28   b  which are angled and which mutually intersect and surfaces  28   c  and  28   d  which are angled and which mutually intersect. The surfaces  28   a  and  28   b  provide for multi-point contact with the arc-shaped contact  36  of the upper bus bar  32  and the surfaces  28   c  and  28   d  provide for multi-point contact with the arc-shaped contact  36  of the lower bus bar  34 . 
     FIG. 5 illustrates an isometric view of upper bus bar  32 , being identical to lower bus bar  34 , where all numerals mentioned previously correspond to those elements previously described. A guide bar  42  is located transverse to the planar surface  44  at the top region of the bus bar  32 . The guide bar  42  aligns in a channel  156  on one side of the upper contact guide  46 , accommodatingly located in the rectangular recess  110  in the enclosure top  14 , to facilitate to and fro movement of the upper bus bar  32 . A similar arrangement exists between the lower bus bar  34 , which is inverted, and the similarly constructed and inverted lower contact guide  48  accommodatingly located in the rectangular recess  86  in the enclosure bottom  12 , to facilitate to and fro movement of the lower bus bar  34 . It is noted that surface  158 , which is located on the bottom of the upper bus bar  32 , is smooth and comes into intimate and sliding contact with the corresponding smooth surface  158  of the inverted lower bus bar  34 , thus allowing for and promoting independent sliding movement of the upper and lower bus bars  32  and  34 , respectively. 
     FIG. 6 illustrates an isometric view of the enclosure bottom  12 , where all numerals correspond to those elements previously described. 
     FIG. 7 illustrates an inverted isometric view of the enclosure top  14 , where all numerals correspond to those elements previously described. A series of detent grooves  118   a - 118   n  having ramped depth are located concentric to the circular recess  116 . The balls  66   a  and  66   b  which align to the upper region of spring bores  152  and  154  on the upper side of the cam  54  align in the deepest region of opposing detent grooves  118   a - 118   n  to provide for detented orientation of the cam  54 . Ramping of the detent grooves  118   a - 118   n  provides for easy and reduced force exit of the balls  66   a  and  66   b  during repositioning of the cam  54  by the solenoid  16 . 
     FIG. 8 illustrates an inverted isometric view of the cam driver  60 , where all numerals correspond to those elements previously described. Shown in particular is the recessed portion  124  and the engagement hole  126 . The recessed portion  124  provides for accommodation of the cam driver arm  56 . 
     FIG. 9 illustrates an isometric view of the carrier driver  62 , where all numerals mentioned previously correspond to those elements previously described. The carrier driver  62  includes vertically aligned cylindrical spring mounts  140  and  142  extending from its top surface for mounting of the lower ends of the springs  64   a  and  64   b  and also includes a plurality of ratchet teeth  144   a - 144   n  located along and extending downwardly from the bottom surface. Also included is a centrally located locator hole  160  which is incorporated for accommodation of the annular centering extension  148  extending downwardly from the cam  54 . Such accommodation provides for vertical alignment of the cam  54  with and over and about the carrier driver  62 . 
     FIG. 10 illustrates an inverted isometric view of the cam  54 , where all numerals mentioned previously correspond to those elements previously described. Shown in particular is the annular centering extension  148  and an annular space  162  located about and between the annular centering extension  148  and the cam lobes  146   a - 146   n . The annular space  162  is also bounded by a planar and circular annular surface  164 . The annular space  162  accommodates the body of the carrier driver  62 . Opposing bores  166  and  168  extend vertically through the body of the cam  54  from the circular annular surface  164  to concentrically meet and align with the spring bores  152  and  154 , respectively. Opposing bores  166  and  168  accommodate spring mounts  140  and  142  of the carrier driver  62  of FIG.  9 . Spring mounts  140  and  142  connectingly interface with the bores  166  and  168  so that rotational motion of the carrier driver  62 , as driven by the cam driver  60 , provides for corresponding rotational movement of the cam  54 . The lower ends of the springs  64   a  and  64   b  align in the respective spring mounts  140  and  142  and the springs extend through the spring bores  152  and  154  where the opposing upper spring ends forcefully align with the balls  66   a  and  66   b  (FIG. 2) to force the balls  66   a  and  66   b  into the detent grooves  118   a - 118   n  (FIG.  7 ). 
     FIGS. 11-14, each illustrates a partial side view in perspective of the bi-stable battery switch  10 , where all numerals correspond to those elements previously described. The enclosure bottom  12 , the large switch terminal  20  and other members have been removed for the purpose of clarity and brevity. Addition of member elements, especially those elements involved with rotation of the cam  54 , are progressively added as shown in the sequenced views of FIGS. 11-14. Shown especially in FIG. 11 is the cam driver arm  56  attached to the solenoid core  128  and the position of the cam driver arm  56  with relationship to the cam pivot pin  58 . FIG. 12 illustrates the elements of FIG. 11 with the addition of the cam driver  60  over and about the cam pivot pin  58 . The cam driver arm  56  aligns in the recessed portion  124  of the cam driver  60  and the cam driver pin  57  aligns in the engagement hole  126 . Pulsed actuation of the solenoid  16  provides for stepped counterclockwise rotary motion of the cam driver  60  about the cam pivot pin  58 , as previously described. FIG. 13 illustrates the elements of FIG. 12 with the addition of the carrier driver  62  and the springs  64   a  and  64   b  extending vertically from the spring mounts  140  and  142 , respectively. Particularly shown is the engagement of the cam driver  60  with the carrier driver  62  where ratcheting clutch engagement occurs with actuation of the solenoid  16 , as previously described. FIG. 14 illustrates the elements of FIG. 13 with the addition of the cam  54  over and about the cam pivot pin  58 . Cam  54  is shown in the position calling for a continuous circuit through the bi-stable battery switch  10 , or in other words, none of the cam lobes  146   a - 146   n  is in direct contact with the cam surfaces  40  on the upper and lower bus bars  32  and  34 , respectively; and the springs  52   a - 52   n  residing in the rectangular spring holder  50  urge the upper and lower bus bars  32  and  34  into intimate physical and electrical contact with the contact  28  as well as the contact  26  (not illustrated). 
     MODE OF OPERATION 
     FIGS. 15 and 16 best illustrates the mode of operation of the bi-stable battery switch  10 , the present invention, where all numerals correspond to those elements previously described. FIGS. 15 and 16 illustrate a cross sectional top view through the large switch terminal  20  U-shaped structure  20   d  of the bi-stable battery switch  10  where the enclosure top  14  has been removed and where a portion of the horizontally oriented structure  20   c  of the large switch terminal  20  is shown in dashed lines. FIG. 15 illustrates the bi-stable battery switch  10  in the conducting mode where the cam lobes  146   a - 146   n  of the cam  54  have been rotationally positioned by pulsing of the solenoid  16  and are not directly influencing or in contact with the cam surfaces  40  of the stacked upper and lower bus bars  32  and  34  comprising the bifurcated contact assembly  30 . The plurality of springs  52   a - 52   n  in the rectangular spring holder  50  are in direct contact with the rear surfaces of the stacked upper and lower bus bars  32  and  34  to directly urge and force contact of the stacked upper and lower bus bars  32  and  34  across the contacts  26  and  28 , thus completing the through electrical contact across and between the small switch terminal  18  and the large switch terminal  20  to make battery power available for a vehicle or other object. FIG. 16 illustrates the bi-stable battery switch  10  in the non-conducting mode where the cam  54  has been rotated by pulsing of the solenoid  16  to overcome the force of the plurality of springs  52   a - 52   n  to rotationally position one of the cam lobes  146   a - 146   n  of the cam  54  into direct contact with both of the cam surfaces  40  of the stacked upper and lower bus bars  32  and  34 , thereby repositioning the stacked upper and lower bus bars  32  and  34  to interrupt contact of the stacked upper and lower bus bars  32  and  34  across the contacts  26  and  28 , thus terminating the electrical contact across and between the small switch terminal  18  and the large switch terminal  20 . Each time the solenoid  16  is pulsed by actuation of a hand held remote signaling device, electrical contact across the bi-stable battery switch  10  is made or broken to supply or interrupt supply voltage from a host battery. Although both positionable bus bars  32  and  34  are springingly and simultaneously urged toward and into intimate dual contact with the stationary and wide contacts  26  and  28  located on the small and large switch terminals  18  and  20 , one positionable bus bar precedes, in a very short time span, the adjoining positionable bus bar and picks up the arcing load in contacting the stationary and wide contacts  26  and  28  of the small and large switch terminals  18  and  20  only to be closely followed by the remaining positionable bus bar which in contacting the stationary and wide contacts  26  and  28  of the small and large switch terminals  18  and  20  picks up the current load. Conversely, when contact is broken by rotational repositioning of the cam  54 , one of the positionable bus bars  32  or  34  leads, in a very short time span, the adjoining positionable bus bar and releases the load current in breaking the contact across the stationary and wide contacts  26  and  28  of the small and large switch terminals  18  and  20  only to be closely followed by the remaining repositioning bus bar which releases the arcing load contact across the stationary and wide contacts  26  and  28  of the small and large switch terminals  18  and  20 . 
     FIG. 17 illustrates the incorporation of the present invention, the bi-stable battery switch  10 , into the top portion  180  of a storage battery such as used in an automobile or in a variety of other objects. A negative terminal  182  would attach to the negative plates (not illustrated) of the storage battery, and, for purposes of example and illustration, another terminal  184 , a switched positive terminal, would connect to the large switch terminal  20  at the horizontally oriented planar structure  20   a  utilizing attachment hole  24 . The small switch terminal  18  would connect to the positive plates of the storage battery utilizing the horizontally oriented planar structure  18   a  at attachment hole  22 . In the alternative, another terminal  186  could attach to the attachment hole  22  if it is desired to have limited battery power available for other items such as burglar alarms or other accessories not related to disabling the delivery of battery power to a vehicle.
