Abstract

The switching device has a pressure resistant switch chamber (11) and an attached switch housing (19) containing the switch operating device (34). The switch chamber (11) contains two pairs of fixed contacts (12,13) and cooperating bridging contacts (14,15) controlled via operating rods (16,17) projecting into the switch housing (19). The rods are depressed against a return spring bias to operate the bridging contacts (14,15) via the operating device (34). The movement of the operating device (34) is coupled to the operating rods (16,17) via a pair of spring-loaded couplers (24,25) with respective arms cooperating with the operating device (34).
