To provide a non-contact switch that can clarify a position at which operation input is received and improve the sensitivity of detecting the operation input.SOLUTION: A non-contact switch has: a stereoscopic display unit 11 that can display a stereoscopic image 21 indicating a position to receive operation input; a light guide plate 13 that is arranged on the back side of the stereoscopic display unit 11 and directs illumination light toward the stereoscopic display unit 11; a light shielding unit 12 that is arranged between the stereoscopic display unit 11 and the light guide plate 13 and in which a pattern 22 indicating the position is formed; a detection unit 14 that is arranged on the back side of the light guide plate 13 and has a light emitting device 141 emitting sensor light and a light receiving device 142 outputting a detection signal upon detection of the sensor light; a first reflection member 181 that has a reflection surface formed in a convex surface shape with respect to the light emitting device 141 of the detection unit 14; and a second reflection member 182 that has a reflection surface formed in a concave surface shape or in a planar shape with respect to the light receiving device 142 of the detection unit 14.SELECTED DRAWING: Figure 6

    【課題】操作入力が受け付けられる位置を明確化するとともに、操作入力の検知感度を向上することが可能な非接触スイッチを提供する。【解決手段】非接触スイッチは、操作入力を受け付ける位置を示す立体像21を表示可能な立体表示部11と、立体表示部11の背面側に配置され、照明光を立体表示部11の側へ向ける導光板13と、立体表示部11と導光板13との間に配置され、その位置を示すパターン22が形成される遮光部12と、導光板13の背面側に配置され、センサ光を発する発光素子141とセンサ光を検知すると検知信号を出力する受光素子142とを有する検知部14と、検知部14の発光素子141に対して凸面状に形成される反射面を有する第1の反射部材181と、検知部14の受光素子142に対して凹面状または平面状に形成される反射面を有する第2の反射部材182とを有する。【選択図】図6
