UlincosMomentary Push Button Switch U19A1 1NO SPST Silver Stainless Steel Shell Suitable for 19mm 3/4" Mounting Hole

Would this be fine for 24v ac/dc?

I have switch wired to led lights and works the light come on but button does not power off, could I have a bad switch or wrong wiring?

can it be painted gold color?

What is the thread pitch on the switch? If you needed to replace the jam nut or tap new threads to match, what would it be?
