D1 d2 d3 1n4148 n1 n4 ic 4093 t1 8050 t2 bc547. The counter circuit is a cdb490 type and is capable to show at pin 12 states 1 and 0 that depends by the pulse applied of pin number 14. We look forward to helping. Like us on facebook. The above design can be further simplified using just a couple of nand gates and a relay on off circuit. Parts required for making a simple touch sensitive switch circuit.
A very simple touch switch circuit diagram can be constructed using this circuit schematic. We just touch the sensor lightly. D1 d2 d3 1n4148 n1 n4 ic 4093 t1 8050 t2 bc547. First the gnd vcc and rst pins of the 555 i e. R3 r5 2m2 r4 10k c1 100uf 25v. The entire design can be witnessed in the following diagram. The lamp cycles between maximum and minimum power in a period of 6 5 secs. When the plate is touched for longer periods the load i e. In this circuit two ics are used one is 555 timer ic and the second is d flip flop 7474 ic. Relay 12 volts spdt.
The design of the touch on and off switch circuit is very simple. Like us on facebook. Stop at the point where relay activates. R1 r2 100k r6 1k.

D1 d2 d3 1n4148 n1 n4 ic 4093 t1 8050 t2 bc547. It makes the current flow through the circuit is changed. To make the touch plate cut a 1 square cm thin metal sheet. When the touch plate is touched briefly from 50 400ms the lamp or load toggles between on and off.
If the relay is in the activated state initially then do the same until the relay is deactivated. Touch switch circuit diagram. Two touch plates are connected to pins 2 and 6 as shown in the circuit diagram. R3 r5 2m2 r4 10k c1 100uf 25v. It makes the current flow through the circuit is changed. In this circuit two ics are used one is 555 timer ic and the second is d flip flop 7474 ic. Pin 2 is pulled high using a 3 3 mω resistor and pin 6 is pulled low using a 1 mω resistor. We look forward to helping. This touch switch circuit is composed from an current amplifier and a decimal counter circuit. Pulses applied to pin 14 are provided by the current amplifier formed by that two bc.
