If your vario has cruise, climb, and auto functions, and you plan to install
a switch in the stick grip, I would recommend a three position switch. My
partner and I did this on our LS-6 about 20 years ago and it worked just
fine.

Forward for cruise,
Back for climb,
Middle for auto mode

Thank you Alexander. The ski pole grip might be a good idea, I will look
what is available locally. I think some DH bike grips might also be
interesting. However, I still would appreciate a ready-made, tested and
robust solution.
