Display lamps 32 and 33 such as LEDs are mounted on the left and right as a pair. One of the paired display lamps 32 is, for example, red, and the other 33 is green. For example, a red lamp indicates that the tact switch 31 is in an ON state, and a green lamp indicates that the tact switch 31 is in an OFF state.

On the other hand, for example, four tact switches 31 are provided on the printed circuit board 30, and each tact switch 31 is operated by pressing a button 35, respectively. The bushing button 35 is exposed so as to protrude through an opening formed on the surface side of the main body case 20, and the bushing button 35 that protrudes
is covered with a transparent or colored translucent guard cap 36 to form a switch operation section. guard cap 36
is retained by being locked onto the bushing button 35, while the space between the guard cap 36 and the bushing button 35 may be used, for example, as a name display section for operation switches.

The guard cap 36 is extended so as to protrude from the opposite side ends of the bush button 35 to both sides, and this extension portion 3
6a and 36b cover a pair of protrusions 37 formed on the front side of the main body case 20. This protrusion 37 has a lamp guide hole in the center of which a display lamp 32, 33 is inserted and accommodated, and the top of the protrusion 37 functions as a stopper for regulating the amount by which the bushing button 36 is pressed. This stopper may be constructed by the edge end of the guard cap 36 engaging with the side groove 38 around the protrusion 37.

Further, on the back side of the printed circuit board 30, a pair of up terminals 42 as signal terminals, an address switch 44, and a load number setting switch 46 are provided, respectively.
