push button wall switch recommendation for smart relay (feddit.nl)

Hi!

I have a MINI-Z1-3CH smart relay (link) that seems to have low voltage inputs for the switching.

I'd like to use it for my kitchen lightning, and have several momentary push buttons wall switches wired to S1, S2 and S3 to control 3 zones, but I haven't found many (86mm standard), so I'm writing here in case someone would have suggestions.

What I've found is often switches meant for AC high voltage with led lights included in the button, so I'm guessing these won't be a good fit. But maybe I'm wrong and something can be done with these (example here)?

Any existing AC switch would work fine, it's just a contact. The built-in LEDs maybe not.

Thanks, maybe I should at least give one a try.

What worries me is that the led implies that a tiny current flows between the wires (maybe permanently?) and that could perhaps be an issue at the zigbee switch input level (maybe it's around 3 to 5v), leading to things like false positives, heat, whatnot ?

But let's see....

A normal 1-gang electrical switch (without a LED) would work without this concern.
