Abstract

An actuator (10) for actuating a vacuum switch tube (11) comprising a fixed contact (12) and a movable contact (13), comprises

a bearing plate (14) that can be fastened to the fixed contact (12);a main spring (15) having a first end (151) with which it can engage the movable contact, and a second end (152);a return spring (16) having a first end (161) with which it engages at the bearing plate, and a second end (162);an actuating lever (17) having a first engagement area (171) at which the main spring (15) engages with its second end (152), and having a second engagement area (172) at which the return spring (16) engages with its second end (162);whereinthe actuating lever (17) is swivelably mounted on the bearing plate (14) such that the actuating lever (17) can assume a first end position in which the main spring (15) is at least partially relaxed and the return spring (16) is tensioned and in which, in particular, the movable contact (13) is disconnected from the fixed contact (14), and a second end position in which the return spring (16) is at least partially relaxed and the main spring (15) is tensioned and in which, in particular, the movable contact (13) is pressed against the fixed contact (14).
