Touch-sensitive rotary switch
First Claim
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.

Abstract
A touch-sensitive rotary switch is configured to be touched along a rotary path, thereby turning on or off, or adjusting stepwise the magnitude of power supplied from, an external power source. The rotary switch includes a housing whose top portion has a sensing surface. A touch control circuit board is provided in the housing and topped with a touch control circuit layer whose peripheral region is divided into multiple sensing areas in which plural first light-emitting elements are annularly arranged. The sensing areas can be sequentially triggered by touching the sensing surface along its peripheral region, so as for the corresponding portion of the touch control circuit layer to control light emission of the first light-emitting elements corresponding to the triggered sensing areas and to output a coded signal according to the triggered sensing areas in order to control the power supplied from the external power source.
