Been working on these throws for stub switches.
I felt the brown one in back was too large, so I made one a little smaller.
Works kinda like a Harp Switch Stand.
Thinking that with a little modification it would work on a 3-way stub.

I'm thinking that a strip of styrene on top of the stand with three notches for left-center-right to lock the throw into position.

Of course I need to build a three-way stub switch first to find out if it works.

Been busy building regular stubs and getting track laid on the Salt Flats/Manly Siding section.

And, need to plan out a building for Si's Salt, along with a couple of boxcars to haul the salt.

Some think me crazy - others just cheap, but I would say don't over engineer the switch stands.
Your prototypes look pretty stout.
I made some out of card stock and wood!

The angles at bottom and the oval tops with notches are card stock.
The uprights are basswood.
The pivot is on a straight pin and throw bar is brass wire.
After adding thin CA to harden them they are pretty sturdy.
Card stock is so easy to work with.

I agree with adding notches to lock in position.
The pivot pin could be in a slot allowing you to lift handle move and press back down into notches.

Attached is a picture of one of mine.
Only fiddly part is determining the distance between pivot pin and throw bar point so that the throw is correct for track movement.

Bob,

Very nice switch stand, and nice switches too!

My concern in  using your construction materials is how well it would hold up in the great outdoors.

So far the styrene is holding up fine.  I know it looks very basic, but it works.

Using brass may be an option.

Could be made out of plastic.  Just a little more difficult to cut out.
