Abstract (en)
[origin: EP0432286A1] In known key switches, the braided cables of a control line are laid individually to electromechanical switching elements (1), and the latter are partially connected to one another via wiring links. The individual line connection is designed as a screw connection, which necessitates considerable installation cost. In the invention, each electromechanical switching element (1) is plugged into a base (2). Provided on the base are solder, plug and/or screw connections for connecting the switching elements to one another and to the control line. <IMAGE>
