I have the TruTrack Altrack altitude hold in my RV-8, but the LED in the control switch has failed.

TruTrack no longer support this AP, so I'm looking for a replacement.
It has two terminals for the switch and another two for the LED illumination.

I can't seem to find anything like that on Digi-key.

Has anyone else needed to replace this and found a suitable substitute?
Maybe a spare lying on the shelf somewhere.

Plan B is to just wire another LED annunciator on the panel, but just looking for a straight replacement as first preference.

I think an ebay search for a lighted push button switch would work. I got one two years ago. Green push button.... about a half inch across. It lights up bright enough for day use.... Sorry, can't remember the vendor name.

Search Digi-Key for LP0115CCKW015DB

Thanks for finding that. I've ordered one of those.

Digi-Key has such a vast catalogue that I failed to home in on the right part. I guessed it would be there somewhere!

TruTrak sent me the bulb when I burned mine out messing with it. Easy to replace and make sure you have the resistor wired in or it will instantly burn out.
