ABSTRACT:
An electrical switch includes a body having one open end exposed for adaptation of a pyrotechnic cartridge and the other end sealed by the base of a pin type connector assembly having short conductive pins and elongated conductive pins with relief areas containing insulative material. The pins are inserted into the body cavity. A conductive grounding plate or plates have tabs which bite into the pins and connect selected pins in a first operational state. A plunger having fracturable bosses is located adjacent the contact plate. Upon activation of a pyrotechnic cartridge, pressure is applied to the plunger, causing fracture of the bosses and resulting in the displacement of the plunger to move the contact plate to a different position thereby changing the number of closed circuits.
