Switching contactor for direct current motor for window lifter, has coil core designed as permanent magnet, and control unit adjusting direct voltages, where cut-off current is directed opposite to exciting current
Switching contactor for direct current motor for window lifter, has coil core designed as permanent magnet, and control unit adjusting direct voltages, where cut-off current is directed opposite to exciting current
The contactor (1) has a coil core designed as a permanent magnet, and a control unit (2) for adjusting two or multiple various direct voltages. A switching armature (7) is movable between a holding position and a resetting position to open and close a switching contact (10). One direct voltage is an exciter voltage for generation of exciting current, which enables coil force to move a switching armature from the return position to the holding position. Another direct voltage is a cut-off voltage for generation of cut-off current, which is directed opposite to the exciting current.
