ABSTRACT:
An object of this invention is to provide a lever operating device for a switch in which the distance between a lever and an actuating element is reduced. According to the present invention, a lever is swung, a transmission member is swung, so that an actuating element is moved to operate a switch. In this connection, arms of the transmission member are made equal in length to each other, so that, as the lever swings, an engaging pin swings the same distance as the actuating element moves. Hence, by setting the distance between the shaft pin and the engaging pin of the lever to the movement distance of the actuating element, the latter can be moved a predetermined distance required for operating the switch, even when the arm of the transmission member is short.
