Efis rotary switch

[kurt-olsson]

Hi.

Does anyone know if there is a 30 degree and 45 degree rotary switch with build in encoder with pushbutton that is lockable at any position like a normal rotary switch. I am having trouble with drilling in my normal rotary switches.

I would gladly pay more if there was a component with everything build in. I found this:

The "ceramic rotary switch" looks like it t i dont know the angle or if its lockable.

Where did you get your efis dual rotary switches?

Hi kurt ..

I know it's not the "real way" the EFIS works (they don't have encoders), but I drilled a normal 30 degree rotary switch and place a encoder behind it using brass shafts. I drill my rotary switches with a lathe, also had very frustrating attempts using normal drill press

also .. check out http://anderssimparts.com/ ... He is also in Sweden and would definitely be able to help you out. he makes some cool dual concentric stuff !

I did something similar when building an EFIS. I used brass tubes of differing diameters. I did not place my encoders "behind" the rotaries because I wanted dedicated buttons for the center buttons in the knobs (so I could fix them in position so they would NOT turn when the knobs were turned). I then geared the encoders so the button shaft could pass through the rotary switch and be fixed to the button. The shaft on the rotary switch was first cut off and then the housing was dismantled (carefully done inside a large ziplock bag so the spring and ball bearing wouldn't be shot into orbit) then I drilled the center to tightly fit the tube through.

I know it sounds a little confusing but here are some pictures.

That looks really good. I drilled my rotary encoder as well for the button, with another 2mm shaft going through all of them to a tactile switch at the very back, so rotary switch and encoder can turn independently without "rotating" the button on the front

Some good work there !

Same result....different tactic.
I also used concentric tubes through one another. I didn't see how to drill through the encoder so I moved it out of the way and used gearing.

There's more than one way to skin a cat and even a blind squirrel finds a nut now and then.
