Abstract

The housing (1) of the electromagnetic switching apparatus contains a switching magnet, stationary contact pieces (2) and moving contact pieces (4) which are fitted on a contact support (3) which is guided displaceably in the housing (1). A transmission lever (11) is arranged between the armature (7) of the switching magnet and the contact support (3). The transmission lever (11) is supported pivotably and displaceably in the attraction direction of the armature (7) in the movement plane of the transmission lever (11), by means of its one end (12) on the housing (1), and by means of its other end (13) on the contact support (3). The central region of the transmission lever (11) is supported rotatably on the armature (7). A spring (10), which presses the armature (7) away from the contact support (3), is located between the contact support (3) and the armature (7) which can be displaced therein in the attraction direction. This spring (10) ensures that the armature (7) occupies the intended position in the switched-off switching apparatus and that the two ends (12, 13) of the transmission lever (11) rest on the seating surfaces under spring pressure. In the switched-off position, the contact support (3) which is loaded by the restoring spring (15) is supported on a stop which is provided on the housing (1). <IMAGE>
