Best durability micro is old FREEPORT.ILL (now honeywell but new is not good as old). Black casing and green or grey plunger, terminals never have mildew or patina. looks like new after 15 years and work. it is truee is blamee mini spring on micro, but meny micro unused spring: KWJ and FREEPORT.IL. They act longer, and has same push and sound |

The internal spring loses its snappy quality eventually. At times, the actuator has a some wear too... but mostly, its the spring that fails. Its very conceivable that mechanical failure is tested and rated. Not to say that everyone does this... but its actually something that is a requirement on something like say.... the military would in fact ask for before ordering Any of such switches. --- End quote --- In that event, the switch would have specific MILSPEC ratings and cost 20 to 30x more. It would still be rated based on the power handling capabilities, as the mechanical life is expected to go well beyond the life of the contacts. In cases where extra longevity is required, like in the military example you gave above, mechanical aspects would be beefed up to meet them. One example would be the use of a coil spring, rather than the thin, flat metal "springs" used in the Cherry switches previously offered by HAPP (and also used in the newer E-Switch model) In an arcade environment, you would never see a contact failure that was associated with the ratings given by the manufacturers, unless they were used in a door interlock system for the cabinet power, or something similar. Of course any switch will fail over time, and it stands to reason that when a switch does not fail due to contact burning or pitting (or heat from arcing, etc) the failure will be associated with metal fatigue. And with no way of knowing how many times those switches were actually depressed before failing, this really doesn't say anything significant. In any event, here's something you should appreciate, Steve; The E-switch is a blessing in disguise. The design is very similar internally to the Cherry switch, but just different enough to allow it to be modified in a way that the Cherry can't. Here's a hint....real leaf-switch-style performance ;D. More on this soon.... RandyT |

I want to see what's going on inside these new E-Switches and how they differ (if any) from the Cherries. |

Randy, Personally, I really do not care too much about the micro differences. I was merely making an point about mechanical failure. As long as the micro is not too hard to depress, nor too easy (usually too easy = fails much quicker), then its decent enough for the mame cab use, Imop. I think Ive recall having a micro that had dual coil springs. I think it was actually a really nice switch actually. As for micro to leaf modification... I personally do not think the performance and feel will be equivalent... but who knows. The biggest drawback is actually the Happ button assembly itself. The Wico buttons have a very narrow center shaft, which not only makes the buttons much more quiet (happs have that horrible hollow sound), but also makes for less slop and smoother travel. I was quite surprised at how much better they feel and react that a standard happs button. (The buttons max depth is a little too much however, which is understandable considering the nature of typical leafs) |
