Along with Chris, I totally agree that your design is brilliant. I tested
both versions (long and short) and both prooved to be very stable with my
switch points. At least after 200 tests. To be honest, I oil my switch points
with pure vaseline oil, as mentioned in a former message
(http://news.lugnet.com/trains/?n=21873) and this reduces very
significantly the effort needed by the motor to action the switch point. It
may contribute to the mechanical stability of your system.

Thanks, Philippe. I must say that it was your article at the FreeLUG site that
got me thinking along these lines. I remember having to search all over the
place when I was working on my first motorized switch!
Here’s the latest version of the 4x6 switch unit:
In this version, the base attachment has been enlarged and strengthened and
another 4x6 plate was added to the roof. The three 1x1 plates from the previous
version were also eliminated as I considered these to be a source of weakness.
I built four of these and all of them are holding together very well. I’ve been
using the transparent 2x3 panels from set 4561 as I’ve found these to be a lot stiffer than the other opaque panels I’ve
tried (besides, it just plain looks cooler with the transparent panels... :-).

I will have to try the vaseline oil on one of my switches, as this switch is
very difficult to throw because of internal friction.
Cheers,
Mark
