That makes more sense smile

I think you said before that the middle position selects both pickups. If that is the case, when the switch is closed (connected to ground) the preamp is not active. So in your above diagram, far left the blue is active, middle both are active, far right the red is active.

You can do it with a three pole on-off-on switch. Connect the center terminal to ground, left terminal to blue, right terminal to red.

This one should work: https://www.stewmac.com/Pickups_and_Electronics/Pedal_Kits_and_Parts/Mini_Toggle_Switches_SPDT.html (#7465)
