    摘要： A rotary switch has a synthetic resin substrate on the surface of which a plurality of fixed contacts are arranged in a concentric fashion, and a holder rotatable over the expanse of the substrate, including the fixed contacts. A conductor plate supported to the holder is formed with swelled contacts which act as movable contacts. A rib is positioned so that the conductor plate contacts the rib when the switch is in the off position, thereby lifting the movable contacts from the surface of the substrate. A substantially hour glass shaped slit is used to separate and insulate the fixed contacts. The wide portions of the slit act as reservoirs for conductive wearing powder, thereby delaying a short circuit due to wearing powder accumulation. Thus, the switch alleviates wear of the movable contacts and enhances switching accuracy.
