Abstract
A parallel wound electric motor is connected to the operating device of the breaker by gears, and cams act on microswitches to control the operation. An electromagnet is used for latching the main driving disc every 180 deg. There are two cams on a shaft connected to this disc. On opening the cct. the first cam controls two switches and the second cam controls one switch which is switched on when the camshaft rotates and the first switch worked by the first cam is switched off. When the disc and the cams have finished rotating through 180 deg. a second switch is held on by the first cam.
