Looking to replace LEDs with solenoid driven indicators. Answered
I'd really like to replace some LED indicators with physical on/off indicators, like they used on old NASA spacecraft. To see what I'm talking about take a look at this console from Apollo 14 at the little windows above the switches at the center left. The top row is all "barber poll" the bottom row open.
My initial thought is that I could possibly replace the LEDs with a solenoid that would shove an "on" indicator into a little window when powered, and retract it when powered down.
The problem: I know next to nothing about solenoids and don't know if this is feasible. They'd need at least 1/4" throw and to run at low power if they're going to simply be a drop-in replacement for LEDs. What kind of solenoid am I looking for and does it even exist?
