Abstract
Four switches are arranged at 90.degree. to each other. Each switch has a reversely bent blade having a short leg pivoted on a center terminal and a long leg having its free end normally spaced from a normally open terminal while the reversely bent portion engages a normally closed terminal higher than the other two terminals whereby the normally open terminal of an adjacent switch can be positioned under the normally closed terminal. The actuator handle actuates opposed parallel pairs in unison whereby one of the pair is actuated to close on its normally open terminal when the actuator moves in one direction and the other of the pair is so actuated when the actuator is moved in the opposite direction.
