Zusammenfassung:To provide a pushing type switch unit capable of allowing a switch to sense pushing even if a pressure is applied between a movable part and a light emission element cylinder.SOLUTION: A pushbutton type switch unit comprises a film-like character board 2 provided with a pushbutton part 5, an operation part main body 3, and an operation part substrate 4. In the operation part main body 3, a movable part 9 composed of a pressing element and a light emission element cylinder 11 approached to the movable part 9 are formed. In the operation part substrate 4, a light emission element 15 positioned in the light emission element cylinder 11 and a switch element 14 pressed by the movable part 9 are provided. The pushbutton type switch is provided such that the movable part 9 and the light emission element cylinder 11 are located in the pushbutton part 5, and an upper surface of the light emission element cylinder 11 is formed so as to be lower than an upper surface of the movable part 9, so that when a finger presses a part between the movable part 9 and the light emission element cylinder 11, a tip end of the pressed part is positioned lower than the upper surface of the movable part 9 and the pressing force can be transmitted from the movable part 9 to the switch element 14.SELECTED DRAWING: Figure 5 【課題】可動部と発光素子用筒との間を押圧してもスイッチが押圧を感知できる押圧式スイッチユニットを提供する。【解決手段】押しボタン部5を設けたフィルム状の文字盤2と、操作部本体3と、操作部基板4とからなり、操作部本体3には、押し子からなる可動部9と、可動部9に近接した発光素子用筒11を形成し、操作部基板4には、発光素子用筒11内に位置する発光素子15と、可動部9により押下されるスイッチ素子14とを設け、押しボタン部5内に可動部9と発光素子用筒11とが位置するように設け、発光素子用筒11の上面を可動部9の上面よりも低く形成したので、可動部9と発光素子用筒11との間を指で押圧した場合、押した部分の先端が可動部9の上面より低い位置となり、可動部9からスイッチ素子14に押圧を伝えることができる。【選択図】図5
