Re: [ST] Any sparkies out there?



It looks to me like the relay is permanently open whenever the circuit has
power to it and the switch cuts off the main power supply rather than the
trickle current to the relay. A very strange way of doing it. I can't see
how the relay serves any purpose at all. The most likely option seems to be
that the brown and pink wires from the switch have different resistances
although it's possible the difference is in the switch itself like you
mentioned.

That's just my 2c worth anyway.
