EQUIPMENT CONTROL SWITCH AND SWITCH SYSTEM

To obtain a device control switch that is easy to operate before maintenance work.SOLUTION: A device control switch 2 includes a power relay 11 that switches on and off a power supply to a connected ventilation fan 1, a power switch 7 that switches a connection state of the power relay 11 by pressing the power switch 7, a wireless signal receiving unit 14 that receives a wireless signal from the outside, and a control unit 13 that switches the connection state of the power relay 11 on the basis of a wireless signal received by the wireless signal receiving unit 14, and when first operation is performed by a user, the control unit 13 shifts to a maintenance mode in which reception of the wireless signal is prohibited and the connection state of the power relay 11 is forcibly turned off.SELECTED DRAWING: Figure 3 【課題】メンテナンス作業前の操作が簡易な機器制御スイッチを得ること。【解決手段】機器制御スイッチ２が、接続される換気扇１への電源供給のオンとオフとを切り替える電源用リレー１１と、押下操作によって電源用リレー１１の接続状態を切り替える電源スイッチ７と、外部からの無線信号を受信する無線信号受信部１４と、無線信号受信部１４が受信した無線信号に基づいて電源用リレー１１の接続状態を切り替える制御部１３と、を備え、制御部１３は、ユーザによって第１の操作が実行されると、無線信号の受付を禁止するとともに電源用リレー１１の接続状態を強制的にオフにするメンテナンスモードに移行する。【選択図】図３
