Patent ID: 11744000

Abstract:
A mechanical switch dimming and speed regulation control system includes a double-contact mechanical switch including at least one alternating current live wire input end, and at least one group of normally closed contact and normally open contact mutually short-circuited with each other, a dimming and speed regulation controller including a signal collector and a dimming and speed regulation control circuit, and a controlled device, outputs of the normally closed and open contacts loop-connected with the dimming and speed regulation controller, the dimming and speed regulation controller loop-connected with the controlled device, the signal collector electrically connected with an output loop of the double-contact mechanical switch and the dimming and speed regulation control circuit, respectively; the dimming and speed regulation control circuit loop-connected with the controlled device. The present disclosure implements high-power dimming and speed regulation control of a single live wire by using the double-contact mechanical switch, and overcomes problems of power limitation of a conventional dimming and speed regulation switch and difficulty for an intelligent switch to implement dimming and speed regulation of the single live wire.
