Dramatically Increase the realism of your Cessna 172 flight by adding outboard control panels in place of point and click Mouse or keyboard input.
You can Add up to 20 Toggle and or Rocker Switches to your Flightdeck; Easily and Expensively. Unlike our 2040 INTERFACE that was designed exclusively for Push Button Switches; the 2120 has a built-in 1/4 second pulse generator, thus allowing standard SPST Toggle/Rocker Switches to be connected directly to the 2120 without the use of an outside circuit board. All pulses are created within the 18F2550 USB Chip code.
Just connect the two wires from the Toggle Switch Terminals to the J1 and J2 male connectors located on either side of the 2120 board; Plug the 2120 into an unused USB Port; program with a aircraft function and away you go on your next, more realistic flight.
To make the switch connections to the 2120 board easier, we designed the
2120 to accommodate twenty 2-pin Female Connectors. Just solder the
switch to the two terminals, then plug the connector into the board. What
can be Simplier? We also supply these connectors with your 2120 purchase.
If you need extra, these Connectors can be purchased on our FS Parts Page located at: http://www.desktopaviator.com/Products/parts.htm or from the link below.

The 2120 was designed for EASE of Installation and EASE of Programming. Even if you have limited Electronics Experiance or none at all, the 2120 is the Flight Sim Add-on for You!
By adding multiple 2120s to your computer, you can add 20, 40, 60 or even 80 Toggle and Rocker switches for the Ultimate Flightdeck.
Sense the realism of flipping a toggle switch to turn your 'Fuel Pump' On or Off; MASTER Alt, MASTER Bat; the uses are as ENDLESS as Your Imagination . . .
With Our NEW! '20 Button Pulse Generator'
The 2120 will product one pulse when you flip the toggle switch ON. And a second pulse will be generated when the same toggle switch is flipped to OFF.
Toggle switches can be programmed using FS2002, 2004, FSX ASSIGNMENTS:
Master Battery/Alt on-off
Panel Lights on-off
Fuel Pump on-off ect.
And FSUIPC as:
Toggle Master Battery Alternator
Toggle Taxi Lights
Toggle Avionics Master ect.

NEW! The 2120 on Steroids (Well Sort of)
Well guys; I BLEW IT "Big Time". Steve asked me to design a
new 2120 board. But this time, let it have enough inputs to
easily attach 31 Toggle Switches to ONE Board. Jumping at
this opportunity; I said "Sure Steve, No Problem". All was fine
until I received the PC Board order from the manufacturer,
and to my surprise, there were 12 open copper traces on the
board. Ahhhh! Well, we can't sell these boards as perfect
items (31 toggle switch inputs with 1/4 second output pulses),
but I can offer you the boards, as is, with 19 inputs. But, here
is the Good News, All the open copper traces go to the 17x2
male header connector, so if you are good with a soldering
iron, I'll show you where the open copper traces are and you
can solder a short jumper wire to complete the circuit. What
will you then have? A fully functioning 31 toggle switch input,
2230 board at an unheard of price of only $47.00 (+ Shipping). If these circuit boards were in perfect condition; the 2230 will be selling on our website right now for $67.00 each. So if you have a knowledge of soldering, why not take a change on a STRONG possibility of including 31 SPST Toggle Switches to your flight sim setup and save $20.00 to boot? But, PLEASE don't tell Steve or Coy that I'm selling the boards to you at this deep discount. If Steve finds out, I'll be in BIG Trouble.
Even with the open copper traces, the 2230 is 100% operational. It will be sensed by your computer as a Joystick device and will load the appropriate Driver Software. The board measures 3 1/8 inches by 2 1/2inches. The board also includes a small Perfboard area to mount additional components or to be used as a common connection point for other flight sim switches or panels.
Instructions for the simple repair can be found HERE
