Abstract

The switch automatically stops the electric drive unit at the two end positions between which it is desired to work, and each section of it incorporates a rotary cam (12) acting against the contactor (21) controlling the respective motion. Between the drive mechanism and the cam there can be a reduction gear, so that the angular displacement of the cams is less than 360 deg. The cams can act against levers operating the respective contactors, and each cam can be in the form of a drum with two faces between which the lever fits, joined by a pin acting against the lever (21).
