Abstract
A multipole key switch comprises switching chambers disposed next to each other are each provided with a movable contact bridge, which shortens a pair of contact fingers in each case in the turned on condition. Contact supports for supporting the contact bridges are formed at a cross-web of an actuating arm. Each switching chamber is provided with a restoring spring. The force of only two restoring springs can bring the key switch into its switched-off position. In order to prevent a sideways canting or clamping of the actuating ram, it is provided with two ribs, with the aid of which it is guided in a guide track.
