Electrical interruptor with successive closings and simultaneous openings

摘要

An interruptor device, in the case of which a single push-button successively closes two interruptors during its pushing-in movement and opens them simultaneously when it is released. ??A system to compensate for the restoring force of the slide spring is arranged between a push-button (64) and a slide (71) for operating the interruptors (75, 76), which system has a compensating spring (66) which is supported on two levers (57a, 57b) which can interact with a groove (67) of the plunger (56) when the latter has carried out a sufficient movement. ??This interruptor device is expediently used for controlling motors having two speeds, in the case of which a momentary stop is intended to take place.
