Another 3D print project under way is a 24 position high power (I hope) rotary switch.
This is something I have drawn from scratch, and is a work in progress, not even fully designed as yet.
This side will bolt to the front panel of the case and have brass M4 screws holding solder lugs.
And this side will use M4 brass dome nuts as the contacts.
The 4 hex holes in the center will connect to the slip ring of the wiper and each outer one will have the solder tabs on the other side.
The wiper etc is still to be worked out fully and drawn.
The hope is to use this in an antenna tuner amongst other things.
