Abstract

The disclosure provides a door switch that improves visibility. The door switch includes an actuator and a sensor. In addition, the door switch is installed so that when a door is closed, a surface of the sensor and an opposite surface of the actuator are in contact with or close to each other, and when the door is open, the surface of the sensor and the opposite surface of the actuator are separated from each other. The actuator outputs a detection signal. A display part for indicating a reception state of the detection signal is formed on the surface of the sensor. The surface of the sensor has a non-opposite region, wherein the non-opposite region is at least a part of the display part not opposite to the opposite surface of the actuator in the reception state.
