Abstract

An electrical switch for an electric power tool. The electrical switch has a contact system that can be switched between an off position and an on position, and having a movable actuating means or switching the contact system. The actuating means comprises a plunger and a contact piece. The contact piece acts on the contact system for the purpose of switching. A coupling element is provided, such that the plunger can be brought into and out of interaction with the contact piece. The interaction is effected such that it is made possible for the contact system to be switched into the on position and the off position by means of the plunger, and for the contact system to be switched into the off position independently of the plunger.
