Abstract:
1. A touch-sensitive rotary switch, comprising: a housing forming a receiving chamber therein, the housing having a top portion forming a sensing surface to be touched by a human hand; a touch control circuit board provided in a top portion of the receiving chamber, the touch control circuit board having a top surface provided with a touch control circuit layer adjacent to the sensing surface, the touch control circuit layer having a top surface whose peripheral region is divided into a plurality of annularly arranged sensing areas; and a plurality of first light-emitting elements annularly provided in the sensing areas on the top surface of the touch control circuit layer and arranged in a spaced manner along a band corresponding to a peripheral region of the sensing surface; wherein the sensing surface can be touched along the peripheral region thereof to sequentially trigger the sensing areas of the touch control circuit layer, so as for a portion of the touch control circuit layer that corresponds to the triggered sensing areas to control light emission of the first light-emitting elements corresponding to the triggered sensing areas and, according to the triggered sensing areas, output a coded signal for controlling power supplied from an external power source.
