Rob ... does this D1 reversal applies to the version 1 board - the very first version board where it is really not a group buy?

No, it does not. I don't believe I had put any type of polarity indication on the earlier versions.

Hello Robert,
I do not know if you have problems receiving my emails, but I sent few without any answer. Could you please help me since i do not know where is the problem and I really would like to complete this project.
I have assembled all 4 soft switches that I received from you and tested two of them. The problem I have is that when power is connected green Led on the board is lit and blue led on the switch is lit, but when switch is pressed nothing happens - no switching occurs. If I pull the terminator from On to Off position or vice versa than I could hear relay switching, obviously while powered. That is the only way to get switch to switch.
I tested the second board with the same switch and it acted the same way. Didn't want to test other two boards in order to preserve them if I did something wrong. I tested without any load and no fuses are blown. Obviously the power is on since leds are light... Everything seems to work fine besides main function - switching. Nothing seems burned, or problematic...
Do you have any idea what I did wrong
I would appreciate your help very much
Thank you
AR2

Sorry, I have not received any emails. I do check my spam filter every now and then and have not seen anything there either.

I will send you an email and we can continue this discussion offline.

You probably covered this in your emails already, but that's the exact symptoms I had on unit #4 until I corrected the D1 polarity.

The excess voltage causes the pin 3 input on the 4013 to stay high all the time, thus no switching.

Mine also! Only one drawback,......they don't switch
If I apply power to the unit, both the LED on the PCB and the blue ring in the push button lite up. If I press the push button both go out, and so and so on but the relay stays silent. I reversed D1 as was mentioned earlier and I measure 11,94VDC on both units. Is there a possibility that I overheated a transistor

Regards

The switch/flip-flop is working since the LED is changing state when you press the button. If you have a DVM you can check each leg of transistor Q1 to see what's happening. The base of Q1 should match the LED: high when LED is on and low when LED is off. The collector for Q1 should be high when the LED is on and low when the LED is off. If D3 was installed backwards, then Q1 will fail because of excess current. If you have the PNP transistor installed in the place of Q1, then the circuit will not work.

Let me know what you find out.

After inspecting both boards I found the following errors.
On one board I reversed D3
On the other one I mixed up Q1 with Q6

I already corrected the D3 error but still no switching. I'm gonna put everything away for a while and come back on it when I feel less p****d about it.

Cheers
