sp st momentary contact that looks like sp

Why do I have to go searching for the spec sheet? https://image.ylighting.com/is/content/modern/LCPP161751_specpdf

Looks like they are calling for an on-off SPST switch and a momentary NO push button. They have them separate on a single plate. 4 conductors from the fixture.

I don't know how you would do that with a single switch.

YOu don't, but could still do it with two separate switches.

because my question was much simpler
and that is I believe
Somebody has installed a
2p momentary contact switch w center off

Never seen such a thing in a Decora style switch, but that doesn't mean there isn't one out there either, but if so simple fix is to tie the two outputs together then no matter which way you push the switch, you get same output signal and it sort of functions same as a spring return push button would.

I have a small HMI and PLC that would work well. Touch the Scene you want and walk away. Probably a phone app out there some place.

Well, yeah. Isn't that what I said?

It seems to me that the fixture, at $2800, would come with the control switches and plate.

I have an X10 switch that combines on/off and dimming in a single button. Push-on/Push-off. Push & hold to dim or brighten.

That's not two switches. It's a dimmer.

Going a little deeper in technicalities, it has some sort of mini processor inside, that switch is just an input device to the whole assembly. It is programmed to do different things depending on duration of the input signal. The switch mechanism itself doesn't directly switch the output of the assembly like it does for the switches that are the main topic of this conversation are typically used.

Actually this operates the same way except that the switches are remote from the fixture and the fixture contains the mini-processor. I believe the switches are LV. They control the mini-processor through 4 conductors. Line voltage is run directly to the fixture.

If low voltage logic signals are being switched, then ordinary switch contacts for 120 V can be a poor choice.

Another good point to consider.

I was replying to the comment about an X10 control device, but yes I think what you described is about what OP has.
