Question about OOP switch wiring

Typically an OOP switch is single throw double pole.....to give you regular then reverse phase operation.

However if you wired it with an on/on/on switch would that give you regular phase/off/reverse phase??
 
Re: Question about OOP switch wiring

Actually, OOP needs a DPDT, (double-pole, double-throw), switch.

This is my 3rd edit. As I doodle this up, I see there are problems doing this. You can do this with either an on-off-on or on-on-on switch, but either way presents problems depending on whether you have another pickup on or off at the same time. It's not a great idea, but let me doodle up a couple things and see if I can work out the problems.

Yes, you need a DPDT switch.
If you use an on-off-on switch you just have an extra position in the middle that doesn't do anything (pup is off). Using an on-on-on switch effectively does the same thing but instead of just turning the pup off in the middle position (by removing it from the circuit), it shorts it to ground. Same result.
Either way, using a three position DPDT switch can potentially create some problems in actual use if you also have a pup selector switch.
A DPDT on-on is your best solution for phase control.
