OK. Problem corrected. Sorry none of the above. What I failed to show was that I had a terminal strip which I connected the neg return. The problem is that I also connected the positive which completed the curcuit. I now have 2 seperate push buttoms for the lightning bolts.
Thanks
Harold
All moot points - the ONLY way the LED could come on without pushing the button is if there is a short around it or it really is a normally closed button (which could be very likely, even if the package said normally open. Heck, Intermountain managed to get non-sound locos in boxes labeled sound versions).
OK if the voltage were REALLY high it could arc around the switch - but even the Evans universal LEDs would not glow under those circumstances, they'd emulate flashbulbs.
This is effectively the most basic of circuits - power supply, switch, and light bulb. There isn't much to go wrong.
BTW there is no + and - in an AC power supply. And since the LED includes a bridge rectifier, there indeed is no + or - there, either.

We know now .... what voltage is your power supply ?

Finally found it. Try to include more info. Others here might like what you are doing. Forums today make a world wide community.

NIce that it can work with DC, AC or DCC.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
What voltage is your power supply, and what is the voltage rating of the LED module ?
(Edit) - Looks like your Evans Design module is rated for 7-19 volts.
hwolf I will check the strand tomorrow but the switch is a Normally open.

With stranded wire it is possible for a single strand to contact the opposite contact.
With solid wire, possible the wire in one contact was long enough to touch the opposite contact. Very easy to do if in a hurray. I know.
Hi Harold:
Do a simple test:
Turn the power on and then push the switch. If the LED goes out you have the wrong switch i.e. its normally closed. If the light stays on then you have a short across the switch or the switch is no good.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!

Seems very simple to me. You really have a normally closed switch or a strand of wire is across the two switch contacts completing the circuit.
Do a visual on the contacts.
I am wiring the lightning bolt for my project. I have included a diagram of how I wire it. The switch is an open circuit push button. The problem is that when I turned on the power the LED became lite.
As I noted on the Diagram the LED is a universal allowing you to use AC, DC, or DCC.
Is this the problem?
