チを作動させる圧力スイツチにおいて、スイツチ
ケースに一対の光フアイバーをその各々の出射端
面および入射端面がスイツチケース内に位置する
ように設けるとともに、このスイツチケース内に
、前記受圧部材に連動して前記一対の光フアイバ
ー間の光の伝達を遮断する可動片を備えたことを
特徴とする圧力スイツチ。 In a pressure switch that operates a built-in switch by a pressure-receiving member that receives fluid pressure, a pair of optical fibers are provided in a switch case so that their respective output end faces and input end faces are located within the switch case, and a pair of optical fibers are provided in the switch case. . A pressure switch comprising: a movable piece that interlocks with the pressure receiving member and blocks transmission of light between the pair of optical fibers.
