Abstract
An electromagnetic actuating device () having a housing () and two actuator pins () that are supported in the housing so as to be movable independently of each other between a retracted rest position and an extended working position, and locking pins () that hold the actuator pins in the rest position via locking mechanisms and that can be moved relative to the actuator pins in the movement direction of the actuator pins. A force is applied to the locking pins in the extension direction by further spring elements (), and the locking pins are moved in the retraction direction by electromagnetic force application in order to unlock the locking mechanisms. The actuating device is an electromagnet () associated with the locking pins in common and having a reversible direction of the magnetic field, and the end sections () of the locking pins facing away from the actuator pins are provided with bipolar permanent magnets () that are oriented with opposite polarities in the movement direction.
