Greetings Allan,

Would like to build your 5 position switch. Appreciate if you can provide the like to the circuit wiring as the link in your website is broken.



Wow, wonderfull idea, you have a video of the switch? If I have understand, when I put it in start position, when release the key, it go on both position, it's right?
How you has make the serigraphies?
Thanks and ciao

I don't have a video currently but I can post one. The key switch springs back from the start position to the both position as it would in a real Cessna.

The letters and markings on the panel are made with a laser cutter. All of the panels here (https://github.com/allanglen/c172-flight-sim-panel) are made with the same technique.

1) Cut white acrylic with a laser cutter (I use http://ebay.to/2kDLgY0)
2) Spray paint the acrylic black (I use https://www.rustoleum.com/product-catalog/consumer-brands/painters-touch-2x-ultra-cover/matte)
3) Raster engrave the painted panel with the laser cutter. This removes the top layer of paint and a thin layer of acrylic leaving white exposed. The translucency of the acrylic also makes it easy to back light the markings.

Thanks, I don't understand how can work the spring for return the key in both position, but I'm sure that when I will print the pieces and assembly they, I will understand all. Thanks and compliment for your optimum work and thanks for share it with we.
Ciao regards

Here is an animation showing the 5 positions. The last position (where the spring is under tension) is the START position.

This is viewing the key switch from the bottom. You can mount it in either orientation but I mounted it 'upside down' to have clearance from the surface of my desk.

Hi allanglen and thanks for your disponibility.
In the week I will make your 5-Position Key Switch by replacing the printed pieces you have made with mine (i attach a picture of my actual key switch).
