Fellow modelers,
I need some help. I might have made this chore harder than it seems so I thought I would ask. I have 2 questions.
What type and from which manufaturer does everyone use for a DPDT switch to control a turnout machine? Im using a tortoise swtich machine.
Then the part that is sort of stumping me... My bench work is made from 3/4 inch thick furniture grade pine. How do I mount a switch through that so that the thow is useable. I have a number of ideas in my head but I think I might be making it harder that it needs to be. One idea was to get a forsner bit and cut a 1/2 inch deep hole in the back mount the switch box then drill a hole throug the rest of the way to mount the throw. That seems like a lot of work.
I purchased my DPDT switches from vendors on ebay. Mini toggles generally for about a dollar each. But don'the be in a hurry. The vendors are usually somewhere in Asia so shipping took three weeks or more.
For instalation I think you need to mount them in panels made of material about 1/8" thick. I used 1/8" hard board (generic Masonite) and overlaid it with 0.020 white styrene sheet. One quarter inch holes are just right for mounting the switches. I drew track diagrams on the panels and mounted the switches at the intersections. I also put in two color LED'S to indicate the points position. A 1/8" hole is just right for 35mm LEDs.
In the early stages of my layout I had several "control panels" where the turnout selectors were grouped on a main dispatcher's panel or "model board". My original intent was to have a full-time operator on duty but that didn't materalize.
Over the years, I found that remote turnout control was more convenient. In many areas my fascia panel is 1/4" so I use a utility knife carefully, or a roto-zip, or a hole saw to make an opening in the carpet covered fascia to clear the switches. In a few places I had to drill the 1x4 or 1x6 but I try to avoid that where possible.
An example is the single switch, with the cabinet pull to protect the switch and help prevent accidental throws, and the LED mounted in a Lexan polycarbonate "shatterproof" blank switch cover.
I use the polycarbonate ones since they are easier to drill and do not crack if I overtighten the screws. I use brad point drills which make a clean hole.
I have not gotten around to making all the labels yet. These make it convenient to unscrew from the fascia if I need to make changes to the wiring, say to add signals or such.
Where I need more switches I use a two-gang blank cover. In areas where there is a large group of turnouts I'll make a panel out of 3/16 lexan or PVC finished with a diagram of the track layout.
Hope that helps, Ed
I built a frame for a piece of Masonite hardboard beneath the benchwork.
This maintains a common appearance across the benchwork and panel, and protects the edges of the panel as well.

Two layouts ago, I made my control panels using two pieces of plexiglas with a color printed track diagram sandwiched in between. I laid the diagram out in I think Visio because I have that, but you can use anything. In addition to color coding the track lines, and adding text, I also put appropriate size circles to drill holes for the toggles and LEDs. I printed one out in black and white and clamped all 3 layers together to drill out the holes, then when I assembled it I used the color copy. The two layers were held together by the nuts on the toggles. I intended to do the final finishing by makign a frame with a slot down the center of each piece to hold the panel in place, but it never got that far. I just had the panel screwed to the side of the layout structure.
On my last layout, I used Tam Valley Singlets and servos for turnotu control. They have the indicator LEDs and pushbuttons on a small circuit board, and since my fascia was thing MDF, I just mounted them directly on the fascia in front of the turnout they controlled. Except for the two at the spot that was to have eventually had the penninsula attached - for temproary use I just screwed them to a piece of cardboard ripped from a box.

LION has used mini-toggles on 1/8" to 1/4" Masonite or ssimilar.
Switches of him (purchased at All Electronics - an MR advertiser) come with a smooth shank, that is they are not threaded. LION simply puts a glob of silicone caulk on the switch body, and pushes it into the hole from the back. Want to take it out again, just twist it free.

I've purchased DPDT toggle switches from two places. One is American Science and Surplus . . . good prices, but sometimes they are out of stock . . . it depends on what they can buy as surplus. However, their website has always been accurate as to what they have in stock. The other place was mentioned by Lion . . . All Electronics. Both of these places ship very quickly.
