With the release of EdgeTX 2.10 on the 12th of May 2024 came a feature that I’m very interested in.

Unused trim switches can be used as 3POS switches

This means that, as the (meh) prowd owner of a jumper t-lite v2, a controller that lacks on the button/switch side of things, now I can have 8 extra buttons to work with! Out with the trims, in with the possibilities.

How to set it up

We start by setting up the flight mode to use this 3P switch instead of the trims. flight modes list flight mode edit

By creating a logical function with sticky and a button as both v1 and v2 we can create a single button toggle switch. logic switch logic switch edit

Then that logic switch can be assigned to a special funcion, in this case to beep the controller so that we can get some sort of feedback on the state of the logical switch. special function

And finally setup a mix that can be handled by betaflight to beep the drone. mixes

Conclusion

This feature brings a lot of possibilities for low end controllers such as the jumper t-lite. It can be used as as more than a toggle switch, this was just a simple example of what is possible.

I will surely find a use for every single one of the newly acquired 8 buttons on my controller and soon complain about not having more.
