PURPOSE:To reproduce a rotating speed before stopping even if a fan is temporarily stopped by separately disposing the operation unit of a speed controller and the operation unit of a power source switch, thereby regulating the rotating speed of a fan. CONSTITUTION:A control switch contains a speed controller 5 for controlling the rotating speed of a ventilation fan 4 in a switch case 3 for a module mounted on a mounting frame of a wiring implement, and a power switch 6 for turning ON and OFF a power source of the fan 4. The operation unit (operation knob) 7 of the controller 5 and the operation unit 8 of the power switch 6 are separately provided and provided on the front surface of the same case 3. |
