Claims (1)

[Claims for Utility Model Registration] (1) A remote control terminal that receives time-division multiplexed transmission signals from a central control device and drives a load control relay based on control data transmitted in the transmission signals. An address setting switch for setting a unique address is provided in the center of the upper surface of the case in which the terminal circuit is housed, and terminal blocks for signal line connection and load connection are provided protruding from both ends. In a remote control terminal equipped with a cover that covers the address setting switch and load connection terminals on the top of the case, the first engaging part formed on the side surface of the load connection terminal block on the address setting switch side is engaged with the remote control terminal. A first engaging leg having an engaging claw that engages with the case is provided protruding from the lower surface of the cover, and a second engaging leg that has an engaging claw that engages with a second engaging portion provided on the upper surface of the case. The engaging leg is curved so as to cut and raise the end of the cover on the signal line connection terminal block side downward, and a finger insertion hole is provided in the center of the cover into which a finger is inserted when the cover is attached or detached. A remote control terminal. (2) A remote control device according to claim (1), characterized in that a guide groove for guiding the engaging claw of the first engaging leg to the first engaging portion is provided on the side surface of the load connection terminal block. Terminal. (3) Set the case in which the terminal circuit is housed to the dimensions agreed upon for the distribution board of one module, and provide a terminal block for signal line connection at one longitudinal end, and a terminal block for load connection at the other end. 2. The remote control terminal according to claim 1, further comprising a remote control terminal.
