Abstract: A capacitor switching contactor is described which includes a standard contactor, an auxiliary switch, an input terminal block, an output terminal block, as well as resistance wires disposed between the terminal blocks, on the one hand, and the auxiliary switch, on the other hand. The resistance wires are connected to connecting terminals in chambers of the terminal blocks, and largely accommodated in the housing of the terminal blocks.

Abstract: An electrical device of the type which is mounted on a base plate is formed of a plurality of individual components which are mounted on only one portion of a divided base plate. In one embodiment, the electrical device is a multipolar switch and the individual components are plate-shaped elements. The divided base plate is provided with at least first and second base plate portions which are separable from one another along a division which extends transverse to the major planes of the base-shaped elements. The plate-shaped elements are coupled to the first base plate portion, and the second base plate portion is advantageously replaceable in a simple manner such that electrical connections to the electrical device can be configured illustratively as screw-receiving connections, or connector connections. The interchange between various types of second base plate portions can be achieved without disassembly of the electrical device.
