- auxiliary contact piece is a possibility ge ⁇ give a contacting of the two contact pieces to each other first via an intermediate switching of the auxiliary contact piece to be carried out.
- a displacement axis of the auxiliary contact piece should preferably be parallel to the movement axis of the contact pieces that are movable relative to one another. In this way, the contact socket can be protected against the effects of arcing phenomena, such as occur during separation or contacting of the contact pieces.
- ⁇ advantageous way is to provide the auxiliary contact piece, for example, with an area of erosion-resistant material. An erosion-resistant material has a higher resistance to arc phenomena than other contact materials used to form the contact pieces.
- arcing phenomena can be concentrated in a targeted manner on the auxiliary contact piece.
- a protective effect of the auxiliary contact piece with respect to the first contact piece can be realized.

- auxiliary contact piece itself is no longer part of the current path formed by the electrical contact arrangement between the first and second contact piece after switching over. Switching can be done without interruption. Conversely, when switching off the electrical contact arrangement, the auxiliary contact piece between the existing directmaschineie ⁇ tion of the two contact pieces are interposed, so that there is an indirect contacting of the two contact pieces on the auxiliary contact piece. This switching can also be done without interruption. This ensures that, in the event of an interruption of the current path to be opened, arcing phenomena occur between the contacting region of the auxiliary contact piece and the contact pressure region of the second contact piece.

- FIG. 3 now shows the first switching contact 1 so-like second switching contact piece 13 in the switch state "ge ⁇ closed" (ON), that is, by means of the second contact piece 13, the auxiliary contact piece 7 is moved into its end ⁇ position in the female contact. 3
- the Auxiliary contact piece 7 is guided electrically insulated in the insulating arrangement 8. Between the first and the second contact piece 1, 13 there is a direct electrical contact via the contact arrangement 5 located in the groove 4 of the contact socket 3.
- the auxiliary contact piece 7 is not in the switched-on state of the electrical contact arrangement more part of the electrical current path between the first and second contact piece 1, 13th
