looking to find a supplier for some small momentary contact switches for an intercom-doorbell panel. they are small single button switches that push in the front of the panel and have two small screws that a thin phone type wire connects to. it is low voltage. i have been to several electrical supply houses, radio shack and a couple alarm companies. nobody has anything. the opening in the panel that holds the switches measure .548 by .343 inches, or 8.72 by 14.02 mm. best i could get with a digital caliper. heres a couple pics of the panel and switches. kids pulled the buttons out of the switches. grrrr the company that made the panel is out of business.

Couple options come to my mind.

Burdens Surplus Center in Lincoln, NE.

If they don't have what you need try Graingers.

These are push in to mount and might require slight modification to the panel. I put square momentary contact switches into google, then images. Jim

They might need a little file action, Your call, but Looking at the spec and your dims seemed OK. Jim
 
Might look at Mouser Electronics. So many switch options it'll take you awhile to wade through 'em.
 
Probably your best bet will be to rivet a plate over the old switch holes, then drill it for industry-standard switches.
