Abstract
In order to effectively disconnect a contact bridge from fixed terminals, even though the contact bridge may be sticking to the contacts, or may be welded or hang, a plunger-type armature core is slidable within a central sleeve of a solenoid for a travel path which is in excess of the connecting path length of the contact bridge towards the fixed terminals. Upon disconnection, a spring returns the armature plunger and, with it, a switching rod which will pass through the overtravel path length before engaging the contact terminals, if the contact terminals should stick, thus exerting a blow against the connecting bridge and tearing it away from the contact terminals.
