How to make speed brake switch working?

[francesco.doenz]

Sorry for being back again....newbie and age most likely....but after the whole day looking for it I have to ask for help on how to make the speed brake work?...I see where the switch is described in the POH, and there is some talk about mapping the keybord command to a controller .....any help would greatly be appreciated!
Many thanks in advance...!

This aircraft does not benefit from AMS config tech. You'll need to use sim default toggle speedbrake command, defined either as keyboard or joystick event.
