I have some Toshiba Strata VI telephones, part of a system I am bringing back to life. Some of the CO buttons don't switch on at all, or do so with difficulty, and by desoldering a switch from a button location that worked and resoldering to a location that didn't work, I confirm that the mini-switches are the problem.
Now all I have to do is figure out what they are and where to get perhaps a dozen of these.
They are miniature or sub-miniature pushbuttons measuring 0.238" square (6.05mm) and are 0.164" high (4.17mm) from base to top-of-button. There are (4) solder leads pointing down from the corners of the base.
Can anyone identify these switches, and preferably also tell me where to get them?
(Some of the numeric touchpad buttons also work less than well on these, and those use larger pushbutton momentary switches. I would also be happy to know about a good source for those, but that is a secondary problem.)
