/diy/ - Do It Yourself

>>965733
Well I think I solved my question (submitted at 03/22/16(Tue)08:12:46)
I was trying to find something that meet my requirements, searches turned up nothing
So I started to design my solution
Started with a old telephone operator style switch board, with pull and plug
then tried to adapt it to some rotating design so I would not have to unplug and plug all the time, but kept getting shorts in my layout
switched to a set of gears with some parts conductive and others non-conductive so they would all rotate to prevent shorts, which actually worked but was a bit complex and would take more work to figure out how to manufacture
Then realized I could stack them like a lock with outward contact pins to save space
this lead to a rotating pin design, but this time the layers added a new degree of freedom to allow current to go up and over rather then short the circuit
so I started looking for parts I would need to build my clever solution
in may searches I find picture of a rotary switch for old audio systems, looks a lot like my rotating key switch
do more research, find out my idea was done long ago under the name of rotary switches
find the type of rotary switch that should work, 3 pole 9 position type or some other version as many of those positions will be redundant but give my desired functionality
now just need to find where I can buy one that meets my needs

redraw my circuit designs, two revisions one of which was very major, added back some addition back in some functions from ultimate goal list
Then return to post this, being the closet match I found so far
