Claims

[Claims for Utility Model Registration] 1. The main body of the switch is provided with at least a light source that emits light when an object to be detected is detected, and the main body is provided with a light source that emits light when an object to be detected is detected. A photoelectric switch characterized by being provided with an optical fiber that guides the light in a direction different from the optical axis of the switch. 2. The photoelectric switch according to claim 1, wherein the optical fiber is detachably attached to the main body. 3 The main body of the switch has at least a built-in circuit that operates when an object to be detected is detected, and the main body has a light emitting means connected to the circuit in an electrically conductive manner external to the main body. A photoelectric switch characterized by being detachably attached so as to protrude. 4. The switch main body is equipped with at least a light source that emits light when an object to be detected is detected, and the main body is equipped with a light source that directs the light from the light source in a direction different from the optical axis from the light source outside the switch main body. A photoelectric switch characterized in that a reflecting means for guiding is detachably attached.
