摘要:
An electric vacuum switching device having a power drive acting on the actuator rod of a vacuum switch by means of a lever is disclosed. According to the invention, the lever is connected at one end with the power drive and, at a bearing surface situated between its ends, with the actuator rod of the vacuum switch. The other end of the lever is supported in a device which permits shifting the fulcrum by an amount corresponding to the switching stroke of the vacuum switch.
