Trainwreck Impedance switch Wiring method (Stackpole switch)

[Ron Worley]

I've been asked how this switch is wired at least 15 times, and it's tough to explain well. I've ginned up a quick photo with comments on it to help explain it (I hope). I will add this picture to the build guide as soon as I have time to do so.

Ken Fischer did this to distribute the high current of the OT output across more than one gang of the switch to make sure that it was safe and reliable. If you're using a basic Lorlin switch with 3 ins and 1 out, it's a no-brainer. Either way, use your DMM to verify that the lugs connect as I have noted- one member found a switch that had one gang wired completely differently. If so, you have3 extra gang on the switch to choose from- KF used the one on the opposite side for whatever reason (symmetry???)

I have spent time with my dmm and all of them just ohm to the output. The lorlin switch I used looks just like the one you have there. There are 12 pins on the back of it. With each click the next lug ohmed to the output lug...#1 on my switch. No 2 other lugs ohmed out at all other wise. example..lug2 only closed to lug1 and no other lug I checked lug2 to every other lug in every switch position possible. I did this for all 12 lugs?
I really appreciate you taking the time to detail the pic and help me understand this.

Heres the specsheet for the switch suggested in the build guide. I assume we would set it to 4 pole 3 positions for 4-8-16 ohms from the OT. So we could jumper terminal 1-7,2-8 and3-9..or 1-4,2-5,and 3-6..or1-10,2-11 and3-12? If I am see it correctly and one of these combinations would work? Any help is appreciated.
