Ace,
I'm wondering if the possibly the capacitor does not fully discharge so it would seem to re-charge quicker after being hit.
I don't have these switches any longer so I can't experiment. But for the 3 years that I used the setup that Eric mentioned, I never had a problem with not being to able to activate a switch.
Or possibly the capacitor that I was told to use recharges real fast. Here's the parts that the fellow (Bob Nelson from CTT forum) had me use:
A 1N4001 50V Silicon Diode (part #276-1101. Two to a package).
A 100 Ohm, 10W Resistor (part #271-135. Two to a package)
A 4700 uF, 35V Electrolytic Capacitor (part #272-1022. One to a package).
