Need to swap the order of 12 wires
cowasaki:
Ok.... I have 6 pairs of wires which I need to switch to different pre- defined orders. The signal is around 1v or less and there are maybe 10-12 possible orders required. A 12 terminal 10 position switch would do it |O but not likely to find such a thing that would fit in the location required (inside a guitar!). So I'm thinking about switching them using another method but can't think of a reasonable way to do it.
Can anyone else?
IN OUT1 OUT2 OUT3
A1 A1 A2 etc etc
A2 A2 A1
B1 B1 B1
B2 B2 B2
C1 C1 C2
C2 C2 C1
D1 D1 D1
D2 D2 D2
E1 E1 E2
E2 E2 E1
F1 F1 F1
F2 F2 F2

Try googling analog crosspoint switch IC.
Ian.M:
Yep.
If your application can tolerate a couple of hundred ohms on resistance, an analog crosspoint switch could do the job. Ideally 12x12, but you'll probably have to settle for 16x16 due to availability. If you can prune your number of orders down to eight you could use an 8x12 one. It will also need power and a small MCU to read a control input and output a switch control bitmap to the crosspoint switch. The MCU can sleep between input changes so should have no effect on the audio.
cowasaki:
Thanks a full audio one will probably be needed. It is for 3 humbuckers pickups on one guitar. Each humbuckers is made of 2 single coil pickups so 3x2x2 wires. The sound of the guitar can be changed by swapping the wiring round to have coils working in and out of phase, parallel, single coils etc with additional switching a 12 or 16 by 16 would allow most possible configurations.

Qty. 6 small-format DPDT switches?
Something like this?

It would require knowing the "binary" settings for the combinations you need.
Do you need to change them on the fly, or only during some setup time?
