摘要
In an arc preventing apparatus of a transfer switch connected to an inductive load, the movable contact of the transfer switch is stopped temporarily while it is transferred from one stationary contact to the other by means of a rotary cam. The cam is provided with a high point, a low point and a peripheral portion intermediate the high and low points so that while the actuating lever of the movable contact is engaging the intermediate peripheral portion, the movable contact is held stationary.
