Cockpit Push Button

I’m very new to aircraft development and working on my first project. I’m
struggling to understand how to get a push button to work. For example, I’m
looking to start with the battery button (ON/OFF) for a test. Do you know
where I can go to start to understand how this works. Following the SDK
documentation tutorial for push buttons did not seem to work for me.

Hopefully this xml file can be helpful for you. My firetruck cockpit (oshkosh
striker on .to) uses a lot of different switch types. Some of them use the
templates that can be found in Official\OneStore\fs-base-aircraft-
common\ModelBehaviorDefs\Asobo directly and some use custom code.
