Here we’re looking at the back of the panel with the back frame removed. This view is nearly edge-on to the panel proper. I hadn’t started wiring it yet when I took this shot:
One of these days I’ll add a view of the wired side. It isn’t nearly as neat as the electrical engineer’s panel above, but it serves its purpose.
The switches are SPDT submini toggles from Digi-key. The panel is roughly the size of a sheet of letter paper - 8 1/2 X 11 inches.
Firstly I used a 18v power supply with a tap also at 9v. The 9v became a common and then 0v became -9v, and 18v became +9v.
I ran the common as a bus which all the switch machines then tapped into for one side of the power. The +9v and -9v then run to each toggle switch which are SPDT rocker switches.
I mounted these switches directly on the fascia in line with the turnout blades, I don’t bother with control panels as I use walkaround operation with DCC. If I have a crossover I wire them to a single switch which is in line with the closest turnout.
Having said all that - i’m planning a new layout. At this stage I’m planning to use Tortoises with NCE’s Switch-It which also has the ability to use push buttons which i’ll place on the fascia in a similar way to what I did before.
[:D][:D]No they are still shays and slow ,but can pull more,They don’t realy like to run tandom,They both have can motors,but not the same ones,They will work better togethor when I get twin can motors in them, Mike is 15years old and Ike is six months old.[^][^][:)]

The switches are sub-mini DPDTs (I said SPDTs earlier by mistake) from digi-key. I don’t have the catalog number right now - I’m halfway across country from home. But they’re about the cheapest small ones they had. The panel face is roughly 8 X 10 1/2, with the rest of the standard letter sized paper (8 1/2 X 11) hidden in the retaining grooves cut into the frame.

Great Simple solution. I went to electronics school 25 years ago and forgot that simple answer. ( if you don’t use certain brain cells, then the grind of daily living throws out the older knowledge ) Great way with + - 12-16 V to throw Kato Unitrack Switches. Dave
I think it’s called split potential. I’ve also seen throttles built using a similar principle. I did it because the wiring on each switch was easier.
I’m defineitely no expert with electronics. I’ve done a few decoder installs including LED lighting and also built a throttle based of a adjustable voltage regulator.
