Where do you guys get yours from. Many old supplies are being sold with damaged buttons and I would like to replace some broken buttons in mine, without having to buy an entire new front panel for hundreds of dollars or having to canibalize them from another supply. Where do I get replacement white buttons for digits, output on/off, etc. They don't have to be labeled, just the right shape to fit HP power supplies which all have these buttons of a standard size.
I am talking about these guys and color is unimportant:

These are the buttons I need to replace (OCP and OV, to be specific) (I don't care if they are blank white, gray, or whatever buttons as long as they will fit and work):

They don't come as individual buttons but a complete front panel rubber assembly. Of course if you don't care for aesthetics then there is no reason you can't cut some from any spare flappy HP panel of the era and use them with a bit of tape?
If it's purely function then you could even strip down a shitty TV remote control and use the graphite pads and rubber on the back of them - just mount something on top to prod them with.

If the rubber sheet / graphite is not damaged, I've had some good luck using a properly cut piece of an eraser. If you cut it to be slightly bigger than the hole / frame it's supposed to fit in, if doesn't fall out easily either because of the increased friction. Very much a kludge, but it works. If the graphite is damaged, I suppose gluing a piece of foil to this eraser piece might do the trick.

Bump... Still looking for a source for actual buttons, without having to buy an entire front assembly, cutting rubber to fit, or cannibalizing other supplies.

Sorry, I got the impression you only wanted individual buttons and didn't care what colour or labels, etc. These aren't available as the keypad is a complete rubber sheet.
I assumed you tried the obvious Keysight Find-A-Part (http://www.keysight.com/my/faces/fapHomePage.jspx) and your keypad is obsolete? :-//
My HP 6632B keypad is available 06612-40001 for £21 GBP for example.

I am looking for individual buttons. I didn't realize that the keypad is an entire sheet on the 665xA supplies - I thought that the buttons were individual.

Even better, 5040-1735 is the entire keypad exactly what you want and is only £15 quid - and 3 in stock!
