A case(10) is formed as a box shape of which a front is opened. The case has a case body, which is buried on a wall plane, and a cover which is coupled to a front plane of the case body by having a cover penetration hole which penetrates a front/rear plane of the cover. A supporting panel(20) is installed inside the case. A slide panel(30) is slidably coupled to the front plane of the supporting panel in a left/right or lower/upper direction, and is elastically supported by a spring. A depressed unit is formed on a rear plane of an adjusting knob(40). The adjusting knob is slidably coupled to a connection which is cross to a slide direction of the slide panel. A knob body is elastically supported by a spring. The adjusting knob has a rotator which is exposed to a front part of the case through a cover penetration hole of a cover. A main switch(50) is installed inside the case. A push button which is inserted into a recessed unit is installed on a front plane of the main switch.
