12v touch point switch connection?

1, the two ends of a wire are connected to the L1 of the two switches, and the two ends of a wire are connected to the L2 of the two switches. Then use a wire to connect one end to the zero line and one end to the L of a switch, and cut the connecting light in the middle. The other switch L leads to a live wire connection.

2, two ends of a wire are connected to the L of the two switches, and the middle is cut off the connecting light. The L1 of both switches is connected to the ignition line, and the L2 is connected to the neutral line

Touch switch wiring

The rectifier bridge composed of four diodes and unidirectional thyristor VS constitute the main circuit of the switch, and the control circuit of the switch is mainly composed of the integrated circuit M668. The 220V pulsating DC output of the rectifier bridge is limited by R1, regulated by VD5, and about 6V DC output by C1 filter is sent to the 8 pins and 1 pins of the IC respectively for IC power consumption. The human touch signal is sent to the touch sensing input terminal SEN (pin 2) of the IC through M, R7 and R8, and the trigger signal output terminal TR (pin 7) of the IC will output a series of trigger pulse signals, which will be added to the gate of VS through C3 to make the VS light on. Touch M again. 7 The pin will stop the output trigger pulse signal, and the light will be off when the AC passes zero.

External oscillating resistance and oscillating capacitance of IC internal trigger pulse oscillator of R4 and C2. The IC synchronization signal is input through pin 5 after partial voltage of R2 and R3. Pin 4 of IC is the function selection end, now connected to VCC high level, touch function: touch M once, light on; Touch again, light off. If the 4 pin is changed to the low level of the vss end, it is a 4-speed dimmer switch, and the brightness is changed once by touching it.
