Hi Banzai,

it would have been nice if you had given us a bit more input.

Although we know that you want to connect two switches to pin 20 and 21, but please what should be switched with it and which EventIDs did you use?
Furthermore we do not have the information, which simulation you use, which aircraft (standard or addon).

Hi Banzai,

please confirm that the other switches/buttons work fine, only these two not.

If so, count the switches/buttons and outputs (LEDs, 7 segment etc) an tell us the number(s)

REFRESH

Just a other Idea while i read that.
Pin 20/21 are the IC2 connectors.

What happen if somebody create a LCD Display Device but not use it..... Are this 2 Pins then blocked . Or better... What happen if somebody will also create a Input Button or Output LED on 21/21 ??

I know that would be a User Issue.... But maby a beginner not know the IC2 Logic and not see that a not used LCD can "kill" this two pins !
Good Luck !
