Im guessing you are using the BU0836? There is no way, I know of that you would be able to use a latch on/off switch with that. A mom/off/mom could be used in this application. Up for on down for off,

My guess is the toggle is spring loaded and returns to the off position.

Mobius, all the info you need to complete your task is in the link below. There are alternate methods as well, some using only solid state devices. The basic operating principles remain the same for all of them.

Some extra info can be found at: http://www.flightsim.com/cgi/kds?$=main/howto/switches.htm

This one describes one variety of solid state solution.

Norbert,

The problem with doing it that way is that the controller is then sending a continuous stream of pulses (keypresses) for each toggle that is latched on (which can be MANY of them for long periods).  All those pulses are getting sent and read on the buss continuously,.... slowing down your CPU processing and clogging up the USB buss.

Rottydaddy,

Yes...FSUIPC will "ignore" the repetitive keypresses until they change state, but to my knowledge it cannot tell the hardware device to stop actually sending the keypresses.

So those keypress signals are repeating along.

I just can't see that such an approach makes sense.  it seems to beg developing some interference or processing problems.

When there are devices that DO send single keypresses...... this approach seems like a poor way to accomplish the task.  I'd use this particular interface for stuff where a momentary button is really desireable... and use something else (like a Hagstrom KE72) for the toggle type switches.

What I am tactfully trying to say is that for THAT particular controller...... use momentaries...and save the toggles and wafer switches for a different interface.

Thanks for the input guys.  I think I might stick with simple momentary switches and buttons for now.

Momentaries are great for some stuff......... like replys to the in sim ATC, switching views, and other "utility" type functions.

But for switching on landing lights, starting engines, and other stuff...... for realism....gotta' have toggles and wafer switches. 

That little unit looks GREAT for some pots and momentaries though.
