Quoted from Coyote:Okay - thanks guys!
One question - if it possible for a ball to only activate a switch less than 10ms? That seems *extremely* fast for a pinball.
sure. hit a microswitch and look at it on a scope! the thing with microswitches is not so much when a ball hits it stays closed, is that it bounces a LOT when it closes before staying 'closed'.
see jack ganssle's article
http://www.ganssle.com/debouncing.htm
his 'switch O' is a typical microswitch that you'd see in ball troughs etc.
"One actuation yielded 7 clean zeroes levels ranging in time from 12 to 86 µsec, and 7 logic ones varying from 6 to 95 µsec"
quite a lot less than 10ms!
