Abstract:
A battery section switch for a load circuit of a vehicle battery, said battery section switch comprising:a housing;an electromagnet system having an armature and arranged in said housing;an input lead adapted for connection to a terminal post of a vehicle battery;an output lead connectable to a load circuit;a contact carrier connected to said input lead and having a length and a movable contact, said contact carrier being switchable between an open position and a closed position and being pre-stressed into said open position by spring power;a stationary contact connected to said output lead and in contact with said movable contact when said contact carrier is in said closed position, to produce a switched connection between said input lead and said output lead; anda toggle spring device having a first lever attached to said contact carrier and having a second lever seated in said housing that are connected to form a toggle via a middle toggle link, said toggle being coupled to said armature and locking said contact carrier in said closed position in an approximately stretched condition of said toggle,upon excitation of said electromagnet system, said armature releasing said locking between said toggle and said contact carrier, andsaid contact carrier comprising an elongated contact spring having a first end clamped only to said housing and having a second end engaging an outer end of said first lever to form a rotary coupling, and said movable contact being carried in a middle region along said contact carrier length.
