Probably too long of a title, but that is pretty much what I am looking for.
I know this is extremely simple, but want to put a couple of sidings on separate toggle switches and have an LED light when power is applied.
I have the LED going on and off with the toggle, but the Negative connection is still connected to the track when the toggle is off.
I have wired the following;
1. Negative jumper from Transformer (-) to the center post of a DPDT toggle switch
2. Connected a resistor, and (-) lead from the LED (short lead) to the end post of the toggle switch (opposite position of switch position)
3. Also connected a Black wire to the toggle switch at the same location as the (-) side of the LED. (To provide "-" to the Siding track.
4. Provided 12v +, to the longer lead of the LED.
What I expected...... Toggle switch ON, the LED lights, AND Negative potential at track siding.
Toggle switch OFF, the LED light is OFF, and NO Negative potential at track siding.
What I get..... Toggle switch On and Off as expected.
Negative potential is ALWAYS on the Black Wire.
Any Advice?
