Electric switch, esp. medium voltage switch for power supply networks

摘要

The electric switch has a pivotable switching lever (6) of at least two parts switchable between a closed position and an open position by an actuator (71). The lever is mounted with a high pressure in the closed position to reduce the contact transition resistance. The lever is held closed by a spring under tension. The spring force is supported at the bearing points (41,51) to form the electrical contact. The spring device acts between the parts (61,62) of the switching lever
