Abstract

The invention relates to electrical engineering and can be used to signal the positions of an output member of an actuator. The purpose of the invention is to improve the accuracy and reduce the complexity of adjusting the device. The switching device comprises a cam 7, a two-part housing 1 and 2 in which microswitches 3 are located, spring-loaded levers 9, one end of which rests on a corresponding adjusting screw 6 screwed into the case and the other has the ability to interact with a corresponding microswitch. Pushers 11 are placed movably inside sleeves 12 and interact with one end surface with a working cam profile, and the opposite one with a spring-loaded lever 9 supported on said end surface of the pusher. The eccentric rollers 13 have a shank that fits into an annular groove made on the outer surface of the corresponding sleeve 12, which has the possibility of axial movement relative to the housing. 7 il.
