ABSTRACT:
The invention concerns an arrangement to couple an auxiliary switch mechanism to an electrical switchgear unit, preferrably a contactor, with a contact slide piece onto which the moving contact pieces are mounted, and a switchgear housing onto which the switchgear fixed-mounted contact pieces are mounted. The contact slide pieces of the switchgear unit and the auxiliary switch mechanism are mounted so that they can slide transversely to the direction of connection. A projection of the auxiliary switch mechanism is positioned in a cutout of the contactor in an interlocking fashion. The connection of contact slide pieces similarly takes place in a positive, interlocking fashion. A lock makes an effective connection with the position of the contact slide piece in the auxiliary switch mechanism, thereby preventing the removal of the auxiliary switch mechanism when the unit is switched on.
