Claims (1)
の可動部領域の片側に発光素子を設け、かつ受光
素子をそれに対向した側に設け、発光素子の放つ
光が前記可動部領域中を通過して受光素子に到達
するように前記光の光軸を一致させ前記スイツチ
を押し下げた時の前記可動部領域中を通過する光
の遮断と前記スイツチを引き上げた時の通過によ
つて変化する前記受光素子の信号を、スイツチの
ＯＮ、ＯＦＦに変換することで機械式接点を排除
したことを特徴とする無接点スイツチ。 In the push button switch, a light emitting element is provided on one side of the movable region of the switch, and a light receiving element is provided on the opposite side, and the light emitted by the light emitting element passes through the movable region and reaches the light receiving element. The optical axis of the light is aligned so that the signal of the light receiving element changes depending on the blocking of the light passing through the movable region when the switch is pushed down and the passing when the switch is pulled up. A non-contact switch that eliminates mechanical contacts by converting the switch to ON and OFF.
