Abstract: A tool handling device for a machine tool has a plurality of tool holders, which are arranged stationarily in one plane. A boom is able to be pivoted around a pivot axis normal to such plane and bears a tool gripper arrangement able to be moved in a radial direction normal to the pivot axis. Tools may be moved by it between a transfer station and the tool holders. This tool handling device is suitable both for use as a tool magazine and also as a magazine extension module for a machine tool to permit high speed tool changing with simple movements.

Abstract: An electric switch having a contact system includes a contact with a contact body (7) and a contact surface (10). The contact is arranged in a recess (25) on a contact carrier (8) in such a way that the contact surface is exposed on the contact carrier (8) and the contact body (7) projects at least on one side (23) of the contact carrier (8). The contact is fastened on the contact carrier (8) by a region (27, 27') of the contact body that is adjacent an edge (28) of the recess (25). The region (27, 27') of the contact body is embossed with the side (23) of the contact carrier.

Abstract: The invention relates to an electrical switch having a contact system which includes a switching contact and at least one stationary contact. The stationary contact has a body and a contact surface which interacts with the switching contact. Furthermore, the stationary contact is arranged on a contact support which has a first wide side and a second narrow side approximately at right angles thereto and in which a recess is located in the first side, which recess has an opening, which faces the switching contact, on the second side. The body of the stationary contact is inserted into the recess in such a manner that the contact surface of the stationary contact is located on the second side. The stationary contact is designed as a bimetallic contact made of a first material for the body and of a second material in the form of a contact facing on the body. The bimetallic contact is arranged as a prefabricated part, with the contact facing as the contact surface on the contact support.
