The invention relates to an electric switch, in particular a rocker switch, comprising a contact system and comprising a movable actuating element for switching over the contact system between two switch positions, in particular an on position and an off position. The switch has a drivable actuator, which is operatively connected to the actuating element in such a way that the actuating element in at least one of the two switch positions is moved, on driving of the actuator, into the other switch position by the actuator for switching the contact system. In particular, the actuating element is moved by the actuator from the on position to the off position of the contact system.
