Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an illumination push button switch capable of increasing visibility of an operation state of a push button by allowing a part to be illuminated to be existed view from a side surface of the switch.SOLUTION: An illumination push button switch comprises: a cylindrical shaped push rod 5 made of a non-transmissivity of which a push button 7 is fixed to one end; a cylindrical shaped frame 6 that is arranged on an outer side of the push button, and is made from the non-transmissivity supporting an axial direction movement of the push rod by pressing the push button; and a light source 13a arranged in an inner space of the push rod of a position where the push rod and the frame are overlapped. In the frame, a frame penetration hole 9 is formed in a peripheral direction so that the light source is matched with an axial direction. In the push rod, a push rod penetration hole 10 is formed so that the frame penetration hole is similar to the peripheral direction. The frame penetration hole and the push rod penetration hole are opposite during lighting of the light source.SELECTED DRAWING: Figure 5
【課題】スイッチを側面から見ても照光する部分を存在させることで押しボタンの動作状態の視認性を高めることができる照光押しボタンスイッチを提供する。【解決手段】押しボタン7が一端に固定されている非透光性の材料からなる筒形状の押棒5と、押棒の外側に配置され、押しボタンの押し込みによる押棒の軸方向移動を支持する非透光性の材料からなる筒形状のフレーム6と、押棒及びフレームが重なっている位置の押棒の内部空間に配置された光源13aと、を備えている。フレームには、光源と軸方向が一致するように周方向にフレーム貫通穴9が形成され、押棒には、フレーム貫通穴と周方向が同一になるように押棒貫通穴10が形成されている。そして、光源の点灯時にフレーム貫通穴と押棒貫通穴とが対向するようにした。【選択図】図5 |
