Thread: Small LED and Switch Wiring

I want to add a few small LEDs to the rear interior that are controlled with a simple on/off switch and connected to permanent power from aux battery.

I have a Traxide kit, so already have a convenient & suitable power feed.
The existing power cable is a 5mm auto twin, fused and grounded to an earth stud (see diagram).
The planned LEDs are 3W each so up to 12W total if I use 4 of them (may use only two).
My proposed circuit is circled in green in the diagram below.
Couple of questions ?.

Ground for Switch - can I just use the Traxide power cable negative wire or do I have to separately ground to an earth stud?

Ground for each LED - can I daisy-chain the earth wires between LEDs and then to the switch ground?

Power for each LED - can I daisy-chain the power supply between LEDs?

The switch is a 20mm diameter eBay special with spade style terminals (see diagram).
Would this typically be suitable for the application I have? i.e. to supply 1A (switch capacity not confirmed in listing).

Cheers,
Scott

Scott.
There is some pretty fash marine gear available to suit your high standard of modifications.
To start with look into a marine busbar to distrubute the power,once its in you can add more with ease.
