BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    This invention relates to a receptacle, and more particularly to a single-molded base to receive a receptacle with a few conducting metal plates formed into a loop mounting therein.  
           [0003]    2. Description of the Related Prior Art  
           [0004]    Conventional extension cords are mostly in multi receptacles, and each receptacle has a separated control switch, a light, or a protective device. The switch controls the conductivity of the plug hole, the light indicates the plug hole is turned on or off, while the protective device is to protect the receptacle not to overload. The wall receptacles of prior arts are also molded with a single separated plug hole.  
           [0005]    All of the above mentioned prior arts are in separates switch control and has a positive and negative connection within the receptacle. However, this design has many confinements, one of which is that he switches and plug holes require a bigger space, further, the design is restrained by its mold which is not easy to change the outfit.  
           [0006]    In view of these shortcomings and others, the inventor has invented the present invention to overcome the shortcomings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0019]    The receptacle with contact points for switch, as shown in FIG. 1, comprises a base  1  for a first conducting plate  2 , a second conducting plate  3  and a third conducting plate  4  to be mounted therein.  
         [0020]    The base  1  has a trough  11  with two sections therein, the trough  11  has grooves  111  (or open space) at one side corresponding to a slot  31  of the second conducting plate  3  and a slot  41  of the third conducting plate  4 . The other side of the trough  11  extends a bridge  12 .  
         [0021]    The first conducting plate  2  is a longitudinal plate having a contact point  21  thereon, and is seating on the bridge  12 .  
         [0022]    The second conducting plate  3  comprises a slot  31  which is seating in one of the sections of the trough  11 . The slot  31  is designed to allow insertion from various directions, and extends a contact end  32  which has a contact point  321  corresponding to the contact point  21  of the first conducting plate  2 .  
         [0023]    The third conducting plate  4  has a slot  41  corresponding to another section of the trough  11  and is also available for insertion from various directions.  
         [0024]    Upon assembled, the two sections of the trough  11  of the base  1  are for the two slots  31  and  41  to seat therein, as shown in FIG. 2. Wherein, the contact point  321  of the contact end  32  is adjacent to the contact point  21  of the first conducting plate  2 , but not contact together. This forms a single receptacle and which may be used as an extension cord or a wall mount receptacle. Due to the special design of the contact point  21  and the contact point  321 , switching device may be mounted in various manners.  
         [0025]    When installed with other devices, the receptacle will require a cover  5 , a switch device  6 , a light indicator  7  and an upper shell A and a lower shell B, as shown in FIGS. 3 and 4. The cover  5  is placed onto the base  1  with holes  51  (or open space) corresponding to the slots  31  and  41  of the second conducting plate  3  and the third conducting plate  4  in the trough  11 . A conducting part  8  is formed in between the contact point  321  of the contact end  32  extending from the second conducting plate  3  and the contact point  21  of the first conducting plate  2  as a switch to the circuit. This conducting part  8  is linked with the switch device  6 . The switch device  6  can be various designs. The light indicator  7  has its two feet  71  connected with the second conducting plate  3  and the third conducting plate  4 , respectively. Thus, when the circuit turns on, the light turns on, simultaneously. The light indicator  7  has neither fixed shape nor fixed place in the receptacle. It is shaped in according to the design of the upper shell A and the lower shell B, so long as its two feet  71  are able to reach and in connection with the second conducting plate  3  and the third conducting plate  4 .  
         [0026]    The base  1  receives the first conducting plate  2 , the second conducting plate  3 , the third conducting plate  4 , and other devices to form the switch unit, which may be used as an extension cord, or a wall receptacle. The single mold may be slid into with a series of single receptacles. There are two ways to form the single extension cord, and they are:  
         [0027]    1. As shown in FIG. 5, take at least two identical single receptacles with the first conducting plates  2  and the third conducting plates  4  connected at their clippers  23  and  42  in series. By following the above process, each single receptacle may have similar peripheral devices, such as the switch device  6 , the light indicator  7  to form as multiple electric power control series receptacle.  
         [0028]    2. Both of the slot  31  of the second conducting plate  3  and the slot  41  of the third conducting plate  4  extends a portion, which form multiple slots  31  and  41  for multiple plugs to use. Peripherals may be installed at the beginning of the receptacle, so that the receptacle has a single switch device  6  and a single light indicator  7 .  
         [0029]    As shown in FIG. 7, the base  1  has a cover  5  with an edge  52  popped out, which then and a rib  13  of the base  1  is formed a receiving section for a cover  9  to mount thereat. Both the edge  52  and the rib  13  have blocks  53  and  14  adapted to engage with a spring  91  thereat, respectively.  
         [0030]    The shapes of the base  1  and the cover  5  may change at anytime, such as FIG. 8. The first conducting plate  2 , the second conducting plate  3  and the third conducting plate  4  are wrapped in the base  1  with the cover  5 . The base  1  has a block  15  with a notch  151  thereat and a trough  16 . The light indicator  7  is placed on the top of the cover  5  with the two feet  71  extending downwardly. The first conducting plate  2  and the second conducting plate  3  may change their shape, such as the first conducting plate  2  extends a contact end  22  with a contact point  21  opposing with the contact end  32  of the conducting plate  3 . Both of the contact ends  22  and  32  are in vertical position. The contact end  32  of the second conducting plate  3  is connected with one end of a conducting part  8  which has a contact point  81  engages in constant with the contact point  21  of the contact end  22  of the first conducting plate  2 . Other then connecting with the first conducting plate  2 , the conducting part  8  may be linked by a linkage  82  to movement in reciprocal and engaging or disengaging with the contact ends  22  and  32 . In this manner, as shown in FIG. 9, the conducting part  8  is secured in the trough  16  between the bridge  12  and the trough  11 , that separates the first conducting plate  2  and the second conducting plate  3  at respective ends. The linkage  82  stays on the notch  151  of the block  15  above the bridge  12  with its inner end engaging with the conducting part  8 , while the outer end extending outwardly. As shown in FIG. 10, the light indicator  7  is secured on the top of the cover  5  with the two feet  71  extending downward and in connection with the second conducting plate  3  and the third conducting plate  4 , thus the light indicator  7  turns on and off with the movement of the linkage  82 .
