Rotary Selector Switches & Resistors

In setting up my console, I set the following parameters to position the lug of the switch in the correct orientation, according to the number of positions the switch will be using, when the positions are centered about 12 o'clock. The only variable is the number of switch functions.

The lug is physically at the six o'clock position, relative to switch position 1. When in QIV, the view is from the operator, looking at the switch from the top; when in QIII, the view is from the rear of the panel.

I normally use Solidworks, but I figured folks that wouldn't know how to do this are more likely to be using Fusion, so here you go:

For absolutely no reason at all, I decided to make it fancy. Now I can choose the orientation of the center of the switch sweep, like noon, 3, 6 or 9 o'clock.

If I were to do this again, I would probably start measurements like a unit circle, with all angular measurements a positive value from the x-axis, CCW. Live and learn.
