Help with Multi-JAMMA Lightgun

[bimm25e]

Hey All I'm  doing something stupid and trying to rig up a 6 in 1 jamma switch in a lightgun dedicated cabinet - I realize that using HAPP guns will allow me to accomplish this as long as i stick with the right boards, I have a bunch of questions about getting the guns to work with the ON board correctly without damaging the boards that are OFF (thinking 6x harnesses with 3x diodes on each).  But today I quizzle you with this:


To get the recoil to work (1 "snap" per trigger pull regardless of game), I'm going to rig a 24v power supply to a solenoid, the PSU will turn on when the game is powered on, thats the easy part,  the tricky part will be sending a burst (maybe .1 second) to the solenoid when the trigger is pulled, all the while not interfering with the trigger signal in any way - bonus points if the recoil is only activated while pointing at the screen .  I am in no way an electrical engineer but I get circuits, I would love to know the parts i would need to use trigger microswitch to control a .1 second "current burst" I was thinking maybe it would be best if i used the "NOT DEPRESSED" side of the triggers microswitch so that no current = burst from 24v circuit.   

thanks for any advice all!
