- Mechanical cut-off contact
The cut-off contact is a switching contact which is integrated into the 7-pin or 13-pin trailer socket. In the trailer socket, two metal contacts are activated by plugging a trailer plug into the trailer socket.
The mechanical cut-off contact is used for the rear fog light cut-off of the towing vehicle.
- Micro switch
The micro switch is an enclosed and waterproof mechanical switch, which has “normally close”, “normally open” and “change over” function. The micro switch is located in the 7-pin or 13-pin trailer socket and is activated mechanically by a switch rocker when a trailer plug is plugged into the trailer socket.
Applications of the micro switch are the trailer identification, the deactivation of the parking assistance system or the rear fog light cut-off/ changeover when towing a trailer.
