摘要： A wireless switch comprising: a movable section provided to be freely displaceable; an operation unit elastically held by the movable section and, when in a non-neutral state, vibrating as a result of an action of elastic force that causes return to a neutral state and displacing the movable section in a direction corresponding to a direction of the vibration; a power generation unit generating a voltage of a polarity corresponding to a direction of displacement when the movable section has been displaced; a wireless transmission unit wirelessly transmitting a signal on the basis of power generated by the power generation unit; and a voltage supply control circuit, when the operation unit in the neutral state has been operated such that the operation unit is brought into a non-neutral state, supplying a voltage to the wireless transmission unit using power generated by the power generation unit at a time of an initial state change of the operation unit and then disabling voltage supply to the wireless transmission unit by the power generated by the power generation unit accompanying the vibration of the operation unit caused by the action of the elasticity afterward.

摘要： A control panel includes power supply circuits for supplying power supply voltages to loads and a connection part for connecting wiring. The control panel comprises a system current detection unit that is for detecting a sudden increase in system current that is from a power system and flows through the control panel and includes a second current transformer, and individual current detection units that are for detecting a sudden increase in the individual current of one of the power supply circuits and include first current transformers. An arc discharge detection unit identifies an arc discharge occurring within the control panel separately from a surge flowing into the system based on a system current detection signal and individual current detection signals.

摘要： A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

摘要： A wireless switch includes a button member, a power generation module, an RF module, and a notification unit. The button member is mounted in a housing, and is configured to move. The power generation module is configured to generate power using energy produced by the movement of the button member. The RF module is connected to the power generation module, and is configured to transmit a switch signal using power generated by the power generation module. The notification unit is configured to operate using power generated by the power generation module. The RF module controls the notification unit in one or more notification states according to a strength or details of a reception state signal corresponding to the transmitted switch signal.
