Comp/Conbrio shower switch

Hello, does anyone know where I can get or have any of these switches for the shower on/off switch (see pics) that were mounted in the rear compartment on the Conbrios? Not sure which year range these were used but mine is a 1990. I assume it was an option that was added later or not at the factory. Or any info on the manufacturer? I have tried to track down similar and all the rest are larger or don't have a light in them. I like these the best for their size and the fact it lights up without having to drill another hole for the indicator light for a different switch. Thanks!

I'm not sure where you might be able to find them, but I would look at the model numbers by the contacts and google those to see what comes up. Digikey maybe has them.
