Adding an L.E.D to rangemaster

[gregaches88]

Hey guys, just wondering which lug of the 3PDT i should use to activate an L.e.d after tapping power off the supply.
and a rough estimate of what resistor would be suitable for this application?


Thankyou

This is the standard wiring practice. See below PDF file.  For a standard 5mm LED  I use  a 4K7 resistor, there are LED calculators online that you can use as well.

Sorry, and welcome to the forum

Yep, that's how I've been wiring mine. 4K7 is a good starting point, but  I've been using lower value resistors. Do a little experimenting before you heat shrink and commit. I like my LEDs on the brighter side.
