- Quick auto sparky qu. Relays.
I have two relays that I want to close with a single closed circuit.
So I though I could connect the relays in series. I thought it made sense. But it appears not so.
If I connect ground at “X” and apply live to point “A” I can close switch 1. But it doesnt close switch 2.
If I apply live to point “B” I can close switch 2, but not 1.
Is there electrcikery inside relays effectively preventing this from working as I think? Obviously I just need to connect them in parallel instead, but just wanted to check.
Cheers for any pointers.Posted 4 years ago
I’m surprised either of them work, you’re only dropping 6v onto a coil which needs ~10v minimum to close the relay!
Mwah. Love you.
I was being dumb and didnt really twig that it needs the full voltage to work!
Thanks. Will wire in parallel.
Chuffed that my heated windscreen test rig with a 10m timer works perfectly. momentary live for on, momentary live for off, or 10m delay auto off!
I need 2 relays as I need 2x 30A, one to each side of the screen.Posted 4 years ago
