Abstract

A low-voltage power switch with a relative auxiliary switch which is actuated as a signalling switch only when the generally multi-pole low-voltage power switch is triggered. The problem to be solved is that of controlling relative auxiliary switches simply and independently of the switch latch. To this end, the switch latch is designed in such a way that the included angle of the moveable contacts or the switching sprindle (18) is greater in the "triggered" than in the "off" state. A radial extension (60) is arranged on the switching spindle (18) in such a way that, in the "triggered" state, it engages a fixed pivoted lever (68) which itself is effectively connected to the prestressed actuating pushrod (66) of the relative auxiliary switch (56).
