12V Illuminated Switch Connection Guide: ON-OFF Function, Diodes, Copper Pin, and Resistor Usage

Hello.

At the beginning I will mention that I looked through the forum and asked my uncle google about the problem that I am now addressing you. Well, I bought switches for 12V, with a diode, as the seller stated on the two-position page (in a telephone conversation he assured that they are ON-OFF buttons). I would add that they did not have technical documentation for these switches.

Product link: http://nowyelektronik.pl/index.php?id_product=93433&controller=product

Switches added a packet, unpacked, connected and was surprised. Namely, I connected the copper pin as ground as standard, the other extreme pin as phase, to the middle circuit with a 120ohm resistor + 3 diodes in series. In each position, the diode on the switches was off, but the system was working properly. I played with different cables connecting to different pins and I have to say that it was not possible to connect the system (except for one exception, about which below) so that the switch in the on position (by default the side of the cradle with the diode pressed) would light when the diode system is working, and went out when I turned it off. That is how it should work.

The exception was that I connected to the 12v copper pin of the power supply, to the middle set of diodes, to the other extreme ground ... Then in the ON position (the side with the cradle diode pressed) the system is off and the control diode is off. In the OFF position (side with the diode up), the control diode on the switch lights up weakly and the LED set also lights up weakly, and the voltage supplied to the LED set is ~ 7.28V.

I have 18 buttons and they all react like that.

Please help.

Connect the "phase" to the middle and the circuit with diodes to the other extreme pin.

Gently undress one of the switches and see what's inside. You will undress them with a small screwdriver. You should put it together without a problem.

I also tried and nothing.

I dismantled and it turns out that after the copper input is 12v, the middle output on the set of diodes and the other extreme is mass.

Problem solved. For people who may come across a similar gives a solution.

Copper pin is a plus. We connect both the power supply and the plus circuit to it. To the middle minus the circuit, and to the second extreme minus the power supply.

Regards.
