Abstract

The invention relates to a touch switch circuit assembly. The touch switch circuit assembly comprises a 12-V direct-current power source, a touch electrode No, a touch electrode OFF, a CMOS (Complementary Metal-Oxide-Semiconductor Transistor) logic circuit, a level overturning and amplifying circuit and a level output end. The model of a dual-input-end four-NAND-gate integrated circuit IC1 in the CMOS logic circuit is CD4011. A mechanical switch is difficult to use with an instrument and an automatic control circuit in a combined manner. According to the touch switch circuit assembly disclosed by the invention, defects of the mechanical switch are overcome. The touch switch circuit assembly is a circuit for replacing the mechanical switch in an electronic manner. The working state of the circuit can be controlled through the touch electrodes on the touch circuit, and the level output end can directly drive a light control circuit, an electric control circuit, a controllable silicon control circuit or a relay circuit and the like.
