ABSTRACT:
An improved electric switch of the type wherein a plunger mounted contactor contacts electric terminals to actuate or deactuate an electric circuit such as a security alarm circuit. The contactor fits into holes defined in the terminals, which are sized so that the contactor contacts the terminals when the plunger is pushed into the switch beyond a predetermined position, or the plunger is released by removing a protection plate, thereby actuating the electric circuit. One embodiment of the invention has a bullet-shaped plunger.
