Battery section switch

摘要

The battery section switch is switched between a terminal post and a main circuit using a contact arrangement. The contact arrangement can be locked in its closed position via a toggle spring device that acts directly on a free end of a contact spring. The toggle spring device is also coupled to the armature of an electromagnet system which, given excitation, releases the interlock and opens the contact arrangement. Given this battery section switch, the on-board network of a vehicle can be quickly switched current-free, given a collision or given a short-circuit, in order to reduce the risk of fire or in order to prevent a discharge of the battery given some other malfunction.
