ABSTRACT:
Two electrically conductive diaphragms which are disposed in generally parallel relation and are symmetrical mirror images of each other are joined to a non-conductive ring. The diaphragms are joined in a pressurized atmosphere of argon at, for example, 3000 psi. When so pressurized internally and with lower external pressure, the diaphragms do not contact each other. When pressurized externally to a pressure to a predetermined level higher than the internal pressure, the diaphragms make contact with each other to close an electric circuit. If pressure leaks into the switch or the external pressure drops, the diaphragms separate and break contact with each other.
