Here, under the explanation of homeopathic behavior, the multi-channel Touch switch consists of NAND gate, charging circuit, Membrane switch and triode.

The NAND gate is composed of two NAND gates in series. The two input terminals of the NAND gate are connected through resistance. The output terminal of the NAND gate is a dual control single live wire Touch switch solution. This solution solves the technical problems of single live wire power supply and dual (dual control) touch function, realizes multi bit and multi way switch modes, low power consumption, and outstanding performance.
