The module can make the beginners learn the principle of touch switch as well as build different circuits. For this module, D2 is electrical resistance of the tuoch end, which with D3 is to prevent the integrated circuits from damage in high touch voltage. C1 is vibration absorption capacitance. R1 is current-limiting resistance. D1 is the inside indicator light. R3 is pull-up resistance. K1 is button switch. Touch the touch end or press K1, HQS0811A will be in reverse state, with D1 indicator light on, the 7 FID outputs high level. When you touch the touch end or press K1 again, HQS0811A will be in reverse state again, and the 7 FID outputs low level. The module can be used alone as well as built as circuit with other modules.
