The invention relates to an electrical switch, in particular for a motor vehicle, such as for an electric parking brake in the motor vehicle, having a movable operating member, in particular in the manner of a rocker, and a contact system, such that the operating member interacts with the contact system in a switching manner. The operating member interacts via an operating element, which is loaded with an elastic force, with a slotted link for generating a resetting force during the movement of the operating member out of an inoperative position. A further slotted switching link is provided. The operating member has a further operating element in such a manner that each of the two operating elements interacts with one slotted switching link each.
