To provide a safety switch capable of upgrading the worker's safety during maintenance to be performed inside a door to which the safety switch is attached.SOLUTION: A safety switch 200 includes: a designation unit that designates an operation mode of the safety switch 200; an output unit that outputs a mode notification signal notifying whether the operation mode of the safety switch 200 is a maintenance mode; an input unit that inputs a display control signal based on a system operation mode which is an operation mode of a switch system 5 including the safety switch 200 and other safety switches 200; and a display unit that performs display on the basis of the display control signal. When the display control signal based on a system maintenance mode, which signifies that at least one of the operation modes of the safety switch 200 and other safety switches 200 is set to the maintenance mode, is inputted, the display unit displays the fact that the system operation mode is the system maintenance mode.SELECTED DRAWING: Figure 6 【課題】安全スイッチが取り付けられたドアの内部でのメンテナンス時の作業者の安全性を向上できる安全スイッチを提供する。【解決手段】安全スイッチ２００は、安全スイッチ２００の動作モードを設定する設定部と、安全スイッチ２００の動作モードがメンテナンスモードか否かを通知するモード通知信号を出力する出力部と、安全スイッチ２００及び他の安全スイッチ２００を含むスイッチシステム５の動作モードであるシステム動作モードに基づく表示制御信号を入力する入力部と、表示制御信号に基づいて表示する表示部と、を備える。表示部は、システム動作モードが、安全スイッチ２００及び他の安全スイッチ２００の動作モードの少なくとも１つがメンテナンスモードに設定されたことを示すシステムメンテナンスモードであることに基づく表示制御信号が入力された場合、システム動作モードがシステムメンテナンスモードであることを表示する。【選択図】図６
