Thank you for your prompt reply.
I will try to be as clear as possible.
I am using the cessna 208 caravan airplane in FSX.
On the instrument panel of the caravan airplane, you have a small selector called DME NAV 1/2 SELECTOR.
I am trying to operate this selector using a toggle switch from my hardware instead of the mouse.
When I assign "DME toggle1" or "DME toggle 2" to a toggle switch of my hardware, I don't see the little DME selector moving from DME1 to DME 2 position.
To answer to last question, The assignment process is working perfectly using either FSUIPC or the FSX assignment feature.
So far all the assignment I made using FSUIPC are successful, but I don't see the selector moving!
Also,
Reagarding the caravan instrument panel, there is a selector Called "Voltmeter/Ammeter" on the left side of the panel.
You have four positions available, GEN, ALT, BATTERY and BUS.
This selector is not listed in FSX assignment page, and I have not seen it in the FSUIPC list neither.
The selector can be operated using the mouse though.
How I can create an assignment to a hardware that will operate the selector without using the mouse?
Thank again for your time.
