Abstract
Abstract Disclosed is a slide switch in which a slide is slidable between a first position and a second position. A holding arrangement holds the slide in the second position when the slide has moved into the second position and permits the slide to return from the second position to the first position after a given lapse of time. A manually operable lever covering the slide serves to operate the slide. The lever is held at least at one position and forms a recess sufficiently large to enable the slide to return from the second position to the first position.
