The 3 way lever switch is what is known as a Double Pole Triple Throw switch or DPTT for short. The switch is composed of 2 internal banks of contacts, Pole A and Pole B. Each pole is either side of the common contact number in the centre. Whatever position the switch is in the middle contact ( 4 ) is connected to a variety of the other contacts on the switch.

Connect your main Hot Out / Positive cable to the central contact of the switch. As this contact stays connected at every position of the switch its the one we use the carry the signal onward into your control circuit ( volume and tone pots in other words ) So connect your main cable up to our contact number 4 then ownard to the rest of your volume and tone circuit.

You need to wire a couple of little jumper wires across between contacts 1 and 2. Also a second jumper wire needs to be wired up between contact 6 and 7.

Now connect the hot wire ( + ) from your bridge pickup to contact number 1.

Then connect the hot wire ( + ) from your neck pickup to number 7.

JOB DONE. You have now wired in your Warman 3 way lever switch to select bridge pickup on its own, bridge and neck pickups on together, or the neck pickup on its own.
