Urgent: How to wire horn to 2-prong switch

I bought a 2-prong igition push button switch to use as a horn button. How can I wire up my GG Train horns to this? THey have a valve with 2 wires coming off of them.

I have wired up switches before, but they have always been 3-prong on/off type switches not push on let go and it is off. If anyone has a drawing or diagram or even just a written explaination it would be great. Thanks, I hope to get this done on my lunch today so I can scare a coworker!

One prong needs power from a 12v source.
The other prong goes to the trigger wire of you solenoid valve (mine is red).
It doesn’t matter which prong goes to which…

Hope that helps.

Wow…thats easy. Thanks man!

you’re welcome

It worked like a charm, thanks again.
