Abstract
A redundant switch includes a housing, an actuator, and a slide movable in the housing in two opposing directions. The slide is coupled to the actuator by two antagonistic springs. The switch includes a latching track with latching notches. At least two switch units are arranged one beside the other for simultaneous actuation by the slide. A latching cam is movably guided on the slide and is urged towards the latching track by a compression spring. The antagonistic springs force the slide to move into respective positions when the latching cam slides over an apex between the latching notches.
