Those look like Bill West switches to me.? They are very common in HP gear, particularly of the 70's and 80's vintage.? There was just a thread on here about them just in the last week or so. You should be able to salvage parts from an instrument keyboard of that vintage.? Where are you?
In case you go looking for a key switch parts donor, a (broken) HP 3437A would be a very good (and undervalued) candidate. They are offered regularly at acceptable prices and the Bill West keys in them are not heat-staked to the PCB but only held by a screw-attached bracket, so very convenient for use as replacement parts.
