I've been using a machine with leaf switch buttons for a couple of weeks now and it seems like it will randomly fire off 1, 2 or even 3 shots for one press of the button. This is not a case of holding the button too long and triggering the game's autofire (which is a slow rate of fire compared to what I am talking about); this is a case of a single quick button press sometimes touching off 2 or 3 shots near simultaneously, faster than I could press and release the button 2 or 3 times. I put a microswitch button in place of the leaf switch button and of course, it is always one shot per button press, which is the way it is supposed to be. Is this how leaf switch buttons always work or is there something wrong with the leaf switches? The switches are clean and they appear to be in good condition. I've heard people claim that you can fire faster with leaf switches than with microswitch buttons. Is this what they are talking about? Accidentally firing faster? |

You might want to get in there and widen the gap at the area the leafs make contact a bit. Just gently move them apart a bit. I was big at adjusting the fire button on Defender/Stargate so that not much pressure was required to fire off a shot. The smaller the gap between the contact points, the "quicker" the button will be. Sounds like your gap may be very small. |

I found the problem. I looked closer at the switch where it makes contact and it was very worn at that point, both on the top leaf and the bottom leaf. Being the player 1 fire button, I suppose that isn't a surprise. I swapped the switch with the least worn one in the CP, which was the player 2 start button, which had no visible wear at all, and it works perfectly, 1 shot for each button press, every time. I don't really know why that worn contact points would cause that issue, since it is still just metal touching metal to close a circuit, but it did. Maybe with the contact points being so worn, it allowed the leaves to contact each other in other areas past the intended contact points, resulting in multiple button presses being registered for a single physical button press. |

Initially it sounded to me like the button was "bouncing" and a small gap, like already mentioned, would cause several contacts to be made with one press. |

Maybe it was "bouncing"; I didn't even think of that. But if it was, it wasn't because the gap was too small. Maybe loss of tension in the leaves through excessive use over time could allow "bouncing" to happen? |
