Abstract
Electromagnetic actuator for operating at least one movable contact of a switch into a switched-on position or a switched-off position. The electromagnetic actuator () has a first magnetic circuit for making a movable () and a fixed () pole body move towards one another and a second magnetic circuit, separate from the first magnetic circuit, with a permanent magnet () and a retaining plate (). A switching-off coil () operates to counteract the magnetic field in the second magnetic circuit so that the actuator () can return to a switched-off position. In the axial direction of the actuator (), the switching-off coil () is positioned Gloser to the retaining plate () than the permanent magnet (), as a result of which more effective operation of the actuator is possible. Furthermore, the actuator is constructed from cylindrical elements that are easy to produce and to assemble.
