Abstract: A circuit substrate is divided into a light emitting circuit substrate 60 and a light receiving circuit substrate 70, and they are disposed in a first casing 21 in a two-tier fashion, and the light emitting circuit substrate 60, which is disposed on an upper side, is overlapped with at least a part of an optical system 40. By this means, it is possible to obtain a wider range mounting surface in a small space, and therefore, it is possible to miniaturize a switch main body. In addition, it is possible to miniaturize the switch main body without miniaturizing the optical system 40 more than necessity, simply by changing a disposal configuration of components other than components of the optical system 40 in the switch main body, and therefore, it is possible to prevent lowering of detection accuracy which goes with miniaturization of the optical system 40, and it is possible to detect an object with high accuracy.

Abstract: A concave curved surface 95 is formed on a light inputting surface 93 of a light emitting lens 43, and a convex curved surface 96 is formed on a light emitting surface 94. Only laser light close to an optic axis A is inputted to the concave curved surface 95, and a spread angle is enlarged, and thereby, it is possible to make intensity distribution more uniform, and to reduce an error on the occasion of comparing a received light amount of reflected light with a threshold value, and therefore, even if a light receiving surface is small, it is possible to detect an object with high accuracy.

Abstract translation: 在发光透镜43的光输入面93上形成凹曲面95，在发光面94上形成凸曲面96。 仅靠近光轴A的激光被输入到凹曲面95，并且扩大角度被扩大，从而能够使强度分布更加均匀，并且在比较接收到的场合时减小误差 具有阈值的反射光的光量，因此即使光接收表面较小，也可以高精度地检测物体。
