Abstract

The invention relates to a double-key touch switch. The double-key touch switch consists of a 12v direct-current power supply, a touch electrode No, a touch electrode OFF, a complementary metal oxide semiconductor (CMOS) logic circuit, a level switch and amplification circuit and a level output terminal. The double-key touch switch is characterized in that the CMOS logic circuit consists of a quad 2-input gate and NOT gate integrated circuit IC1, a touch electrode No, a touch electrode OFF, a resistor R1 and a resistor R2. The type of the quad 2-input gate and NOT gate integrated circuit IC1 is CD4011. The double-key touch switch is capable of overcoming defects in a mechanical switch and is a circuit in which an electric mode is adopted to replace the mechanical switch, and working condition of the circuit can be controlled by touching the touch electrode in the circuit. The core element used in the double-key touch switch is the CMOS integrated circuit CD4011. The level output end can directly drive an optical control circuit, an electric control circuit, a silicon controlled circuit, a control relay circuit and the like.

Description
