Korry Switch Surplus

[ak49er]

Gents, I have a few sets  Korry Switches lying around. They are all used, appear to be in good condition, some are on-off some are momentary, all have multiple posts, multiple light sockets, and multiple trigger posts. I am not sure of the voltage of the lamps installed, but I would assume in the 120-140V DC range.

I am not sure how to "step-down" the DC voltage to make the lamps work, or if one should just get replacement lamps.

These appear to be the same size used in the Master Caution Lamps of most aircraft. 30mmx24mm.

The glass is easily removed and the Text Laminate can be replaced with suitable text.

Any one have experience with these?

120-140V DC range !!?

Seems awfully high, Korrys lamps are usually 5V 12V or 24V.
Did you test from 5 to 24?
The best could be  to switch, as Korry themselves do, to LEDs

PS: probably Easterline can provide replacement LEDs, just call them with the part number.
Cant cost that much.
