SPDT and DPDT switches

the difference is that a DPDT lets you do two things instead of one when you throw the switch ... i can give you an example from my own guitar mod .... i have the neck pup on one side of the DPDT and the bridge pup on the other side ... so with 1 flip of the mini toggle, i can control the split of both pickups .. if i wouldve used SPDT switches, i'd have needed one for each pup
i hope this helps

AFAIK:
D.....E.....F
................
G.....H.....I
A Double pole double throw has 2 arms, so in the above switch it could have one from D to E and another one from G to H, and when you switch it it swaps to E to F and H to I... or some DPDTs have one from D to E and one from H to I, and swithc to E to F and G to H.
Hope this makes sense!
A single throw, on the other hand, I think looks like this:
|.......|
B.....C
.........
....A...
....|....
A single pole double throw switch has one 'arm' that has one end fixed, and the other can swing between 2 contacts.... so the signal can go from A to B, OR from A to C
D.....E.....F
................
G.....H.....I

I don't know why, but my 'quick reply' dissapeared.
That was supposed to be an on/on DPDT, like I have on my series/parralel switch and how a lot of stompbox switches work. A DPTP on/on/on would be even more useful, and let me have series/split/parralel wit hthe same wiring, but I can't seem to find one locally.
