EFIS 737NG BARO & MINS rotaries

[pshz11]

Hi,

Today I were advised by 737 pilot about baro and mins rotaries to set value. It is spring loaded mom. rotatary switches, wich acts like ones on CPFlight EFIS, but on CPFlight EFIS they are used to select IN-HPA and RADIO-BARO and that is also not correct. So, my question is where to buy such rotary switches? Video below describes what I mean:

Just Google mom rotary switches. I found several.

Yes, I've also found some, but they are 3-pos all. And EFIS uses 5 pos.

I don't understand. There's two switches on each axis, the lower 2-pole for changing radio to baro and hpa to in, the upper for changing the value, which is your 3 pole mom rotary switch. there's no 5 pole switch that I can see.

As seen on video above, there are 2 detents to the left and 2 detents to the right. first detent (each direction) changing value one-by-one and second detent - increases value by 10 and accelerates. When you release this knob, it centers.

Ah. In that case, never seen them.

damn :( no one that knows? Buying CPFlights pro EFIS is not a option! i will not pay more money since i dont have their MCP. And the Baro selector is a must along with HPA and to make this soo realistic as posible

Hi there!

Finally I have my own solution. Used few parts of rotary switch, others are 3d-printed.
