The external dimensions of the main body 8 formed by combining the body 5 and the lid 6 with the tongue piece 7 having the locking portion are the standard dimensions (JIS C8303 large rectangular boss) of the wiring device 9 such as a switch.
It is formed to have a size twice as large as that of the wiring device 9 and is provided with a locking device which is connected to the wiring device 9 and is locked to the mounting frame 10. The locking means is a pair of claws 11a when locking to the plastic mounting frame 10 and holes 11b when locking to the metal mounting frame (not shown). In the example, both are provided so that they can be locked to any mounting frame. In addition, a terminal (not shown) connected to the wiring device 9 such as a switch serving as a monitoring input is provided. Then, the mounting frame 10 is fixed to the embedding box 12 with screws 13, and a plate 15 having holes 14 is attached to the front surface of the mounting frame 10 to complete the operation.
