Hello, I'm looking for a (physical) switch arrangement that achieves a very particular kind of behaviour:
-- It's a rotary switch, or some arrangement that allows traversing its three states in repeating fashion without hitting a limit and coming back (state 1, state 2, state 3, state 1, ....). Think multimeter dial, except only 3 states.
-- There are 3 inputs (X, Y and Z) and 3 outputs (A, B, and C), and the three states are:
-- State 1: X--A Y--B Z--C
-- State 2: X--C Y--A Z--B
-- State 3: X--B Y--C Z--A ( so you can see it's very much rotating through the (non-reversed) possible permutations )
-- 40V, 3A (as if this wasn't hard enough already)
-- Break-before-make, naturally
-- Not at all fussed about how it looks/how it's mounted.
-- EDIT: I only need one of these; this is a one-off project.
I've seen teardowns of test gear on EEVBlog that have little switches stacked together, all operated by a single shaft running through the whole stack, this might be a promising approach but I'm struggling to find the relevant category on element14 -- and I'm not sure those are "high-power" parts. Any ideas would be greatly appreciated.
