Quoted from Gogdog:
Ok, so you are thinking if I raise the switch vertically it would improve switch hit success?
From your posts a year ago, it looks like your ball issue was mainly fixed by moving the wireframe.
My current theory is that its a problem with the fast moving balls going airborne off the ramp but of course I could be wrong.
If I am wrong...and it is just the ball is moving too fast for the switch to get compressed enough to register...if I move it up vertically it would hit more of the ball surface, though also increase the chance of pushing the ball out of the wireframe...
Correct...the wireframe was my main problem (found using slo-mo video). Tweaking/raising the switch was still useful to avoid the switch hitting the lock nut.
If you can capture the ball jumping the switch with video, you can determine the root cause. In your case, my gut says the plastic ramp leading to the wireform needs to be adjusted.
