Hi guys I’m new here I’m ramsey from the uk,
A hopefully simple question for you,
I have 3 led light circuits in my garden all individually switched and powered, however I’d like them all to be switched on together via a light switch I have got,
Any idea if there’s a relay type switch I could use so the light sensor (it outputs 12v ) could close the circuits simultaneously on 3 independent circuits? Any help would be much appreciated

How much current do the LED arrays draw? This will be a simple task using the 1 relay and 3 diodes large enough to handle the current draw. They will still have independent switching via the 3 switches you have plus simultaneous on via the new circuit.

Not very much at all one circuit has 4x8 led’s Another has 16x3 led’s And the 3rd is a led light strip 4 m long guess about 30 led’s Wouldn’t be more than 40w

Basically I’m looking for a circuit board with 3 relays normally open. All to be closed with 1 input (from light sensor) is there one readily available on the market or would I have to make one ?
