Ahhh, now I see
There are two roller switches!
That's a new puzzle for me too
According to Blaze's post the second one is the safety switch driving the caution light.
Looks like for us pitbuilders this one is not really important, since the lights are controlled by the software anyways...
Ok, I just went and downloaded BMS 4.37 to take a look at the keyfile:
Canopy open, stop and close are for the toggle switch.
The new bit is canopy lock, unlock, which I assume is for the warning light? this will be the roller switch. This one actually is the one which tells the sim the position of your physical spider.
For the time being, there is not "canopy sealing", but I think I am going to add a switch for it as well, just in case it gets implement in the future, but probably it won't be necessary.
I think this settles it?
