PURPOSE:To prevent the trip state of a remote control braker from being released accidentally due to malfunction by providing a lock switch which invalidates a switch input through the operation of a trip release switch, to prevent malfunction. CONSTITUTION:A remote control braker controlled by a control signal transmitted from a centralized control panel 1 is built in a terminal, and electricity is supplied to an electrical appliance through the remote control braker. In this case a trip release switch S1 for releasing the trip state of the remote control braker is provided on the control panel 1. Simultaneously a lock switch S2, which invalidates a switch input through the operation of the switch S1 to prevent malfunction, is provided. Even if the switch S1 is accidentally operated, the trip state of the remote control braker will not be released unless the switch S2 is set to the trip release possible side, and the danger caused by malfunction of the switch S1 can be prevented. |
