Abstract

The invention relates to a touch alternating current power switch. By virtue of a characteristic that a human body induces an alternating current signal and through touch induction of a finger, an aim of turning on or turning off an alternating current power supply is achieved; the touch alternating current power switch is applicable for turning on or turning off an illuminating circuit and electrical and electronic equipment which are powered by the alternating current power supply. The touch alternating current power switch has the characteristics as follows: the touch alternating current power switch does not have current in a ready mode, adopts a serial wiring way that a single live wire goes in and out, without using an additional neutral wire, is operated by a single key, can be used by electrical loads with different powers and different impedances, has the overload protection function, does not change the original input current waveforms of the electrical loads, can automatically keep high working efficiency, is applicable to segmented dimming control of a switch in a modern illuminating system, is free of noise, non-contact, long in service life, reliable in circuit structure and low in manufacturing cost, can be compatible with or replace the conventional mechanical touch switch, and is applicable to manufacture of a modularized, integrated, single-key, multi-key or multi-way switch.

Description

technical field [0001] The invention relates to a touch-type AC power switch, which is an electronic switch composed of electronic components and circuits, and is suitable for power-on or power-off of lighting circuits powered by AC power and electronic and electrical equipment. Background technique [0002] With the rapid development of modern technology, the AC power switch, as a control component of electronic and electrical circuits, is also constantly evolving. The traditional toggle or key-type mechanical contact switches have disadvantages such as high noise and short life, which are insufficient for the needs of modern life. And because precious metal resources such as copper and silver used in such products are in short supply day by day, production costs continue to climb. Therefore, in the long run, it will be a development trend to gradually replace traditional mechanical contact switches. [0003] Today's touch technology is widely used, but in addition to the...
