Abstract
Abstract A slide is movable by an actuating knob back and forth in a rectangular housing and is attached to a movable metal contact below it by elements integral with the slide. The contact is pressed downwardly by a spring mounted in a bore in the slide. The housing, slide and knob are molded from insulating material. A pair of stationary electric contacts are mounted in the bottom of the housing in positions to be bridged by the movable contact when the slide is in a predetermined position in the housing. The slide may be provided inside the housing with a pair of integral resilient indexing prongs extending laterally into notches in the side walls of the housing.
