For the firsr part of your question,I’d say yes, you can use the N scale ground throws. However I would check the the amount of travel. Thats the important part. Secondly, the difference between ridgid throw and sprung throw is that on ridgid throw, the ground throw is mounted or attached to the point rails mechanically or solidly if you will, while the sprung version has springs between the throw and point rails. The springs hold the point rail against the stock rail. Ken
Definately. I used them exclusively on a previous HO layout.
Caveat: Check the throw distance on your switches and compare it with the throw on the switchstand. I was using handlaid switches so my throw distance may be smaller than some commecercial switches.
I have used Caboose Industries throws (ground throw and the taller switch stands) in HO since they were introduced. These are produced by a fellow named Aubrey Olson who took the time many years ago to teach me how to hand-lay track.
I definately recommend the “sprung” variety. This gives you a little varience or “wiggle room” in mounting, and will hold the points against the rails for better electrical connection. I agree that the distance of the “throw” is key on whether the N ones will work. With the gauge of 3.5, the throw distance would be less than standard gauge, so there is a good chance that it would work. Although you may have a delay in getting a supply, it would seem worth buying a test unit or two and then deciding from there.
By the way, some of my initial Caboose Industries ground throws have been in use for many years and are now being re-installed on my new layout here in the “retirement house” in South Carolina. They are very durable; I can’t think of ever having one to malfunction without abuse.
If your chief consideration is how they look next to the turnout, I’m afraid you’ll be disappointed.
The physical dimensions of the Caboose Industries ground throws are the same. The only difference between N and HO is the distance the throw bar moves.
I use the sprung version with integral slide switch on my N scale layout. The slide switch allows polarity change on my Micro Engineering turnout frogs.
I mounted the ground throws at the edge of the layout and operate the turnouts with piano wire running through brass tubing. It keeps the out of scale pieces away form the scene.
