Hi,


has one of you ever tried making a multi-position switch directly on the
PCB like most handheld meters have?
I can't gold plate it (yet).
I think tinning would do for now.

I think of using a M6 screw as axis, just a washer on each side to make a
bearing
of a hole in the PCB. Then take a piece of FR4 and make the "wiper" with
contacts
of thin sheetmetal.
The M6 screw would fit into a knob on the front panel.
The "snap" action could be achieved by drilling holes in the PCB and
letting
some spring catch them.

What do you think of that? stupid idea?

It seems i can't get rotrary switches with enough positions.
Would be nice to be able to just make them how i want.
After all it works in meters...

tell me what you thik about that.
