Abstract:
An overcurrent circuit breaker switch having a flat, approximately block shaped housing made of insulating material with first and second front walls and side walls that extend approximately parallel to each other, and a switch gear located between the parallel side walls and having a movement plane in which components of the switch gear move that extends approximately parallel to the side walls of the housing, the first front wall having a bushing for contact connections and the second front wall having a bushing for a device for manual actuation of the switch gear, said switch comprising:a contact bridge support made of insulating material, said contact bridge support being a component of the switch gear;two fixed contacts, each having a narrow edge and a flat piece with a longitudinal axis which extends away from said first front wall into an interior of the housing, said two fixed contacts being spaced from one another and being positioned so that said contact bridge support projects into the space between said two fixed contacts; anda contact bridge movable between an on position and an off position, said contact bridge being held inside the contact bridge support and having a longitudinal axis that extends in a bridging direction which aligns approximately at a right angle to the movement plane for the switch gear, said contact bridge having contact ends that project on both sides over said contact bridge support in the direction of the side walls of the housing,wherein said fixed contacts are flat pieces that are aligned in the manner of a knife blade, are each positioned with a flat side approximately parallel to the side walls, and form respectively one contact point with a side of the narrow edge facing said contact bridge, the contact points being parallel to one another, the other side of the narrow edge of the fixed contacts facing and fitting flush against a flank wall of the housing.
