Abstract
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 ( ).
