ABSTRACT:
A contact arrangement for connecting an insertable power switch to a switching system having a fixed carrier for supporting the power switch, the fixed carrier and the power switch each having respective connecting lugs, the power switch having an auxiliary circuit and being insertable into a predetermined position in the carrier, and the switching system including contact members for effecting an electrically conductive connection between the connecting lugs, and a drive mechanism for moving the contact members into predetermined contact positions. The contact arrangement further includes a contact frame which carries the contact members and is movable between OFF, TEST and ON operating positions, and a spindle drive which is fixed in the carrier below the location of the power switch; said contact frame is movable to positively connect the connecting lugs of the fixed system portion and the power switch in the TEST and ON positions when the power switch is in the predetermined position in the carrier, the contact arrangement further includes a plug-in contact which is positively moved together with the frame for providing electrical connections to the auxiliary circuit of the power switch; and the frame includes a cover plate which, in the various operating positions of the frame, positively assures a cover for the connecting lugs of the carrier to secure those lugs against contact by operating personnel and tools.
