Push button with LED

(1/2) > >>

Hi all

I have a SPDT push button switch that has an LED installed. I'm attempting to get the LED to illuminate when pushed only AND have the switch complete the audio circuit at the same time. When the button is not actuated, no LED and no circuit. Please see the attached diagram for the lug configuration. The audio circuit successfully completes when the + wire is soldered to N.O. and the - wire is soldered to COMM. Attempting to add the LED into the mix is where I'm struggling.

Currently I've tried a few combinations, but haven't been able to achieve what I need. The latest attempts:

* N.O. > LED+, + wire to COMM, and - wire to LED- (LED illuminates when pushed, LED off when not pushed, no audio circuit made when pushed)
* LED+ > N.O., LED- > COMM, + wire > N.O., - wire > COMM (LED illuminates when button is not pushed, goes off when pushed, audio circuit made when pushed).

I'm starting to think the design of the switch won't allow for what I'm trying to do (maybe a DPDT switch is what I should've bought?)

Input greatly appreciated!

ArthurDent:
A DPDT switch is what you need.

*sigh* I figured as much. Thank you for verifying!

If you can't get a switch in the same format but DPDT, then you could use the switch to switch the LED and a relay, which is used to control the audio circuit.

Revisiting this thread.

I have tracked down and ordered the DPDT version of the push button w/ LED switch.

@ArthurDent - curious... the diagram you posted shows a DPDT switch but you've labeled it as if I was wiring SPDT. Am I missing something here? I would've assumed that needing a DPDT would mean I would use one set of poles for creating the circuit for the LED to illuminate when pushed, and the other set of poles to create the circuit for the initial function of the switch...

Thanks for the help!  :box:
