の検出スイツチ。[Scope of Claim for Utility Model Registration] (1) In a detection switch having a detection circuit section that detects an object and provides a switch output, and a switching circuit that switches the output mode of the detection circuit section, a power supply provided within the detection switch body. A light-emitting element that lights up when turned on; a light-receiving element that is provided inside the detection switch body and provides a light-receiving output to the switching circuit; and a light-receiving element that has a reflective surface on its inner wall and is held in the detection switch body and that is connected between the light-emitting element and the light-receiving element. What is claimed is: 1. A detection switch comprising: an adapter for forming an optical path, and configured to switch an output mode based on disconnection of the optical path by the adapter. (2) Utility model registration claim 1, characterized in that the adapter has a mirror surface formed in the internal cavity and reflects the irradiated light in the same direction.
Detection switch described in section. (3) The detection switch according to claim 1, wherein the adapter includes a half mirror that exposes a portion of the light from the light emitting element to the outside.
