(In a contact (11), in particular a gripping contact for isolating switches, having a copper contact core (13) and a silver contact facing (14), applied to the contact core (13), a high wear resistance is achieved, in particular taking into account the contact-breaking arcs which occur in use, by a further protective facing (15) being provided, which is applied to the silver contact facing (14) and consists of a soft metal, specifically of tin. A further silver contact facing (16) can also be applied to the tin protective facing (15). <IMAGE>
