ABSTRACT:
A high-voltage switch having a housing supported on a pin insulator and two movable switching pieces mounted in the housing. The movable switch pieces of the switch are coupled via actuating parts to a drive transmission element, a crankshaft, for example, which is guided through the pin insulator to a drive mechanism. The drive mechanism includes the crankshaft which is rotated by one crank whose movement is controlled by another crank. The movable switch pieces are very heavy and must be moved back and forth between ON and OFF switch positions. The drive mechanism provides two precisely located stable positions corresponding to the ON and OFF switch conditions and the heavy switch components are moved such that their motion is damped as they approach one or the other stable position whereby the need for additional damping means for arresting the movement of the switch is avoided. The switch is suitable as a multi-phase generator switch having several switch poles.
