Timer

Using a timer switch for electric fans can automatically turn off the power when people sleep or leave, which can reduce the waste of electricity.

Timer Working Principle:
To use the timer, the clockwork is first rotated by a certain angle each time, and the cam turns coaxially with it to turn the elastic contact on the timer spindle. Under the control of the intrinsic vibration-free escapement, it rotates in the counterclockwise direction. The cam follows the spindle. After a certain period of time (i.e. timing time), both the cam and the barrel return to their original position.  When the elastic contact is disconnect, completing the timing time limit, the power supply to the fan motor is cut off.
