A load-disconnecting switch has a permanent-magnetic holding circuit. A coil ( ), upon excitation thereof, generates a magnetic flux that is opposite to the magnetic flux of the permanent magnet ( ). The armature ( ) is biassed to an open position by an armature spring ( ), so that the armature spring ( ), when a defined operational excitation is exceeded, detaches the armature ( ) from the core ( ) of the magnet system, allowing said armature to open and thereby disconnecting a switching contact ( ) and a fixed contact ( ). The load-disconnecting switch can be switched on again by means of a spring clip ( ) acting on said armature ( ).

Load disconnecting switch especially for use in motor vehicles

An electromagnetic relay has a magnet system, a base, a movable contact element, stationary contact elements and contact terminal elements. The base is formed by a printed circuit board arrangement. A first printed circuit board of the printed circuit board arrangement thereby faces toward the magnet system, and a second printed circuit board of the printed circuit board arrangement forms a bottom side of the relay. Each of the two printed circuit boards has interconnects. The movable contact element is actuated by an armature and is arranged between the two printed circuit boards. An actuation element that transmits the movement of the armature onto the movable contact element has a pin-shaped end section projecting through a recess in the first printed circuit board. The contact terminal elements are pin-shaped and project through congruent recesses in the two printed circuit boards.
