Abstract
An electric switch (1) includes a switching device (4), movable between its ON position and OFF position, for switching a current circuit. The switch (1) is combined with a magnetic circuit (28, 29) for electromagnetic undervoltage tripping. In the event of undervoltage, the magnetic circuit (28, 29), as it opens, shifts the switching device (4) to its OFF position. The switching device (4) shifted to its OFF position closes the magnetic circuit (28, 29) again. A linearly movable fixing slide (24) couples the switching device (4) with the magnet armature (28) of the magnetic circuit and fixes the magnet armature (28) on the magnet core (29) in the OFF position of the switching device (4).
