SENCORE PR57 AC POWERITE Switch and Switch Cap Source

[Voxman]

Hello Everyone!
(2nd attempt to post this)
I’m restoring an old Sencore PR57 POWERITE power supply that has 2 switches where the push button caps have broken off. I have one cap but need an additional one. Also I doubt there is enough part of the switch to be able to successfully reattach the caps. The switches involved are all part of an interlocking system however I’m sure they are individually replaceable if I could find a source. I apologize that I don’t have a photo of the actual switch yet but if no one out there knows what type of switch this Sencore uses, I’ll have to disassemble my unit to see what it is ( big PIA because it’s installed in a tight test bench ). I’ve noticed Sencore uses these switches and caps on a lot of their equipment.
Haven’t been able to find any source for these parts yet on eBay and a few of the sites recommended here in the replacement knobs, etc. forum.
Thanks in advance for everyone’s advice and input. I’m even hoping somebody out there might have these parts laying around!
