Abstract

The invention relates to an electromagnetic switchgear, in particular circuit-breaker. <??>With electromagnetic switchgear, in particular contact breakers, there is a significant requirement for constructing the circuit-breakers to be bounce-free. Due to the striking of the contact bridge support at the end of the switch-off process on the housing, particularly when plastics such as thermoplasts are used for the contact bridge support, rebouncing phenomena have been almost unavoidable. The present invention is intended to reduce these rebouncing phenomena substantially. <??>This is done by providing projections on the housing which are of unequal height in the movement direction of the armature, and which can project through openings of the contact bridge support so that the projections can come into contact with a metal part, preferably the armature itself, during switching off. <??>Electromagnetic switchgear with alternating current and also direct current magnet system. <IMAGE>
