Abstract

A power switch includes switch contacts that are opened via a switch shaft, which, when the switch is triggered, is actuated by way of the trigger slider of a trigger unit, in particular a working current trigger unit. The trigger slider moves the switch shaft by way of the trigger shaft of a switch latch, the trigger unit including electric coil into which an armature extends that is drawn into the coil by electromagnetic forces of attraction when the switch is triggered. A stationary counter armature is disposed in the coil, which counter armature serves as a stop for the armature, so as to increase the forces of attraction. The movement of the armature is transmitted by way of a mechanism to the movement of the trigger slider so as to increase the displacement path of the trigger slider.
