Abstract
A contact that has two fixed contact elements and a mobile contact bridge actuated by a switching assembly and is urged by a pole spring. The connection between the mobile contact bridge and switching assembly is provided by a magnetic compensator connected to the switching assembly by means of a magnetic coupling device adapted so that, when the compensating forces rise above a given threshold, the magnetic compensator is disengaged from the switching assembly and becomes inoperative.
