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. A method for producing such a switch is furthermore described.
