ABSTRACT:
The base plate module of an electromagnetic switching device, specifically a contactor, is mounted on a base plate (1). The base plate module contains the core (2) of the electromagnet, a magnet coil (5), a printed circuit board (10) with its connected ancillary devices, as well as the contact plugs (16, 17) and terminals (24, 25), both of which are accessible from the outside. Printed circuit board (10) is mounted on base plate (1) and is located between base plate (1) and core (2), which is mounted on the base plate. Strip conductors (12, 13, 14), on the side facing core (2), feature several spring-loaded stub contacts (19, 20) and/or contact plugs (21, 22), all of which are vertically mounted on circuit board (10). Flange (7) of coil module (6), which is oriented toward base plate (1), provided with terminals (23) of magnet coil (5). With magnet coil (5) in the mounted position, terminals (23) of magnet coil (5) are in contact with the spring-loaded stub contacts (19) of strip conductors (13). Contact plugs (21, 22) serve as receptacles for card (27) which contains electronic circuitry. All electrical connections in the base plate module are made by strip conductors (12, 13, 14) of printed circuit board (10).
