I need some very responsive and easy to operate DMDT momentary switches

If you find a switch that's satisfactory except for its operating force, take it apart and shorten the spring. Pry the retaining prongs out with a small screwdriver and let it pop open over a dishpan. See if this helps. Youtube downloads so slowly over my dialup that I fixed breakfast in its first 12 seconds.

Or you could mount two pushbuttons between a lever, either a T lever on a flat panel or a straight lever hinged to the bottom of a U with the buttons in the sides. jsw

What about slotting the switches and using E snap-rings?

Yes. What you have described is called a microswitch. This used to be a trademark (Honeywell), bot the term is now generic in practice if not yet in law.

Electrically that's a very good suggestion, if you can find them easily.

Mechanically you might want to leave room for another spring to center the control lever because the microswitch springs are very weak.

Really good switches are getting harder and harder to find, because the world is going over to solving all those problems electronically.

The usual suspects here are DigiKey, Mouser, and Newark. All will sell in small quantities. It used to be that Mouser was my go-to place for switches and resistors, DigiKey for semiconductors, and Newark for anything that smacked of industrial. That was 30 years ago, so things have changed a bit.

I think, though, that I'd look at Newark first, then Mouser, then Digikey. Figure that you may have to order multiple different switches and try them out for touchy-feely.

Could you go with a proximity switch?
