Hi jdjuggler,
I emailed Andy at Ultimarc just the other day with the same question.
Here's the relevent parts of his respond.
"Turning over the [restrictor] plate [of the J-Stik] reduces the travel. This is the full mechanical travel. The travel until the switch is actuated can also be reduced by bending the switch levers.
The full travel is either 24mm or 20mm."
I would say this is just barely noticable but I don't have facts to back me up. I plan on getting these for a single player/classics control panel.
jakejake28, the Wico STC 500 looks 'odd' to me. The 2-4-8-way feature is something important to me but I haven't heard anyone comment how easy it is to switch between say 8-way to 2-way vertical. Looks like you need a screw driver. Care to comment? Also, does it do 4-way diagonal?
Cheers,
zero-one
