Abstract: A switching device (Figures 5A and 5B) employs as actuator a bistable solenoid which includes a plunger (16) movable within a winding (12) between end positions in each of which it is held by permanent magnets (18, 20). The plunger (16) of the actuator is engageable with an insulated lever (86) which in turn actuates a contact blade (76) via a spring (108). The lever may be cranked, and may have an extension (90) outside of the casing (70) to enable the device to be manually operated or to provide a visual indication of the state of the switch. Other types of solenoid may be employed as the actuator.
