How does it work
The functionality of this circuit base mainly on the flip-flop action of TR3
and TR4. There are two options of the application i.e. Purely touch switch
(on-off) and semi-action. The explanation will begin with.
Purely touch switch (on-off) : (J is left opened).
When the circuit is first activated (by supplying the voltage) the LED remain
dark. By touching the T terminal TR1 and TR2 start to conduct the current
which make TR3 inaction while TR4 on the contrary begin to let the current
pass through. The LED finally begin to grow. On the contrary, if the T
terminal is touched again the flip-flop action of TR1 and TR2 make TR3 action
while put TR4 in standby. The LED them give no light.
Semi-action : (J is connected).
In this mode, the T terminal must have a constant contact with the finger in
order to turn the LED on. As soon as the T terminal lost contact with the
finger the light from LED goes out.
The explanation of why LED is on while T terminal is touched can be found in
purely touch situation. When T terminal left open (no finger on T) both TRI
and TR2 are in stand by mode TR3 then begin to conduct the current which make
TR4 into sleep mode.
When this happen LED then shows no light. This logic is possible because of J
terminal is connected.
Circuit Assembly
The assembly of components is shown in Fig. 2. For good looking and easy assembly, the shorter components should be first installed – starting with low resistant components and then the higher. An important thing is that diodes, electrolyte capacitors, and transistors shall be carefully assembled before mounting them onto their right anode/cathode of the IC board otherwise it might cause damage to the components or the circuit. Configuration of the anode and the cathode is shown in Fig 3. Use the soldering iron/gun not exceeding 40 watts and the solder of tin-lead 60:40 with flux within. Recheck the correctness of installation after soldering. In case of wrong position, just use lead absorber or lead extractor wire to avoid probable damage to the IC.
Testing
Do not connecting J to each other. Connect the power supply 12VDC to circuit. Touching T sensor 1 time, LED displays and relay works. Taking supply off and connecting J together. Connect power supply again. Now LED does not display. Touching T sensor, LED and relay is start working and will stop when touching T sensor again. Selecting desired function types, if requires 1 touch start and 1 touch stop, do not connecting J together. If requires touching switch on and untouched for switch off, connecting J together.
