Applications
Applied for speed ON/OFF switching and speed select switching in the fans with multi-speed motors.
Design and control
The casing is made of plastic. Provision is made for the direct switching of the motor speeds (wiring diagram 1 and 3 ) as well as fan switching ON and control synchronically with lightening in the room (wiring diagram 2 and 4).
Mounting
Speed switch is designed for indoor wall mounting inside a flush mounting box MKV-2 (under separate order). It can be installed into standard round electric junction boxes.
