I'd like to wire up my speaker cab this weekend, and I have everything ready to go except the basic switch knowledge to get the job done. Here's what I'm trying to do:

Mono, Switchable Impedance
2 Musical Intrument Speakers. Impedance selectable between 4 and 16 ohms by using a switch.

2 - 8 ohm speakers = 4 or 16 ohms depending on which way the switch is set

Here's the layout:

That doesn't match up with the poles on a DPDT switch so I can understand it:

So, can someone do a sketch for me or point me to a site that shows where the various wires need to be connected in order to get the desired configuration? Or maybe describe which poles on the layout correspond to which poles on the actual switch? PLEASE HELP ME! :?

Thanks!

Dean

Thanks,
