Hand-held electric appliance power-saving switch control mechanism

摘要

A power-saving switch control mechanism for hand-held electric appliance comprises a sensor to detect the approaching hand of user and then continuously transmit signals to activate a switch into a close-circuit status in order for a cell to supply power to a control circuit of the electric appliance. When the sensor fails to detect the hand on the electric appliance, the switch returns to an open-circuit status to stop the cell from supplying power to the control circuit and stop the operation of the electric appliance accordingly.
