A switching device for programmable control of electrical and electronic apparatus includes a support plate and a slide switch which is moved along a forked guide track defined on the support plate. The support plate is formed of magnetically conducting material or a magnetic plate is disposed below the support plate. The actuating slide is provided with magnets which cooperate with the magnetically conductive support. Several switching elements disposed along the track, which switching elements, upon being actuated by the actuating member, effect control processes of the electrical or electronic apparatus. The switches may be interrupted conductor tracks, capacitive sensors, proximity switches, light gates, and the like. A symbol plate is disposed above the support plate and the slide is moved along through-openings in the symbol plate which define the switching options. The operator follows the guide of the labels disposed on the symbol plate. |
