Ok RandyT going to dissect your reply earlier, my goal is only to make this a productive discussion
no pun intended dawg

ACTIVATION/ENGAGEMENT POINTS:
I have some old stock of KWJA, a few days back got an order of 100 KWJA from
aracade emulator.net So i have roughly about 400 KWJA's. I also have order of
50 E-switches from happ that came in over the weekend.
I didn't test every single one, but i sure tested ALOT of microswitch comparisons
between the cherry KWJA and the E-switch brand. The activation point differences was
very obvious, as in night and day my friend.
Take the E-switch micro and push the red actuator down until it clicks. It does not click
until it is almost "flesh" with the white plastic on the micro itself! This simple test
repeated same results over and over with little variances.
Now take a KWJA (cherry micro) push the red actuator down until it clicks. It barely even goes
a mm and it clicks away. Again simple test repeated with same results from old and new batches
of KWJA. If you try this with the D44L and D41C they activate jus a teeny bit lower than the KWJA's.
Conclusion: To me if the activation/engagement difference is as much as the "head" of the red
actuator itself, Thats a huge difference, infact enough where it can degrade my gameplay. I play hardcore
fighting games like Marvel vs Capcom2 and precision is a must.

GRAMS OF FORCE:
RandyT, All the invoices i have from previous Happ orders all show the KWJA / 95-0733-01 happ part#
to be rated at 75 grams. Even from cherrycorp site, look at their chart of the breakdown of the
KWJA0017 model# and it'll show KWJ + A = 75 grams.
link right here:
http://www.cherrycorp.com/english/switches/miniature/k.htmRandyT, you say that "HAPP specified the E-Switch to have the same ratings as the KWJA0017 Cherry they used to use"
I find that quite hard to fully believe. I think Happ took the closest E-switch avail to "closely match"
the KWJA0017. Let me explain why. The E-switch LS model is rated at 15 amps while th KWJA is rated at
10 amps. The KWJA is rated at 75 grams of force, while the E-switch brand is rated at 50 grams. The differences plus the fact that the terminals on the e-switch are copper alloy plated vs the KWJA terminals being brass copper(not plated). So to say E-switch has the same ratings as the KWJA is misleading by the least

Conclusion: There is E-switch is a "close" match to KWJA specs but not exact. They may be using a different
method in calculating grams of force between the KWJA and the e-switch causing this discrepency. KWJA is
definitely softer of the two micros.
--------------------------------------------------------
VOLUME LEVEL OF MICROSWITCH:
You mention the E-switch has a higher frequency. This could quite possbily be why is sounds "louder". I would consider this but going back and testing volume levels, The E-switch is noticeably louder vs KWJA. There could be
"different makes" of the KWJA causing this difference. I know cherry has their stuff made in mexico, china, and
even india i think. So it could be one's guess on quality control from those regions
Conclusion: The KWJA is the quiter of the two. KWJA has a "softer" click noise vs the E-switch. Also this volume
level difference is a very minor concern, just something to be mentioned.
--------------------------------------------------------
LONGEVITY/ MECHANICAL CYCLES:
I agree with you on this topic. I remember Happ site when they sold KWJA's to "reliably tested over 10 million
cycles". This was specifically on their site describing their cherry micro's. Even other sites have this same claim with the cherry micro's. I wonder if Happ did this 10 million cycle test or who did it? I don't know for sure if the KWJA really last 10 million cycles, but i know those bad boyz can go for a long time!!!

--------------------------------------------------------
HAPP, E-SWITCH, GROOVY SST
I really give you credit stepping up to Happ about the microswitch differences, really I do! I had done the
same thing when Happ bought up Wico/Perfect 360 joysticks. When Happ took over, quality control fell apart like
a sand house on a rainy day. I went to TRI-STAR plastics to have custom replacement parts made especially
for the P360. There were frictional/grinding issue with the ciruclar hubplate and the spring bearing washer. I
spent a few thousand dollars on prototypes and got it right. Still can't beleive Happ took a great product and
used sub-optimal materials and almost ruin one of the best joysticks ever.
You mentioned, let me paraphrase it, "all it looks like they knew was the printed spec, not what was actually being
made and shipped." Man i wouldn't be surprised if that was the case, seriously i wouldn't!
The Groovy SST sounds like a wonderful micro. If you don't mind me asking who/company made it?
Does it have the snap mechanism or the spring mechanism?
RandyT, right now I am so hyped up to purchase and test out the Groovy SST's , will be checking your site tonight!
So please get them listed or let me know how to get them!

CONCLUSION: It can be possible that specs listed by happ/cherry/e-switch may only be whats printed and not the
"real specs" themselves. So it may be necessary to do a simple test on batches of micros to be sure they are
what you wanted.
PERSONALLY: You would think a any micro would do, I means its just a switch closing a circuit, but the reality
is there is more to it than that for an enthusiast. I may be bold in saying this but i think this is what most people
are looking for in a good microswitch:
1)responsiveness, quick engagement (as you said a "sharp" feel)
2)light pressure to activate, ~50-75 grams of force, maybe even less after i test out Groovy SST!
3)mechanical cycle longevity, if its true the cherry can go 10 million cycles, this fits me superbly
minor qualities:
a)micro click loudness
b)terminal & blade composition materials
Last quick point: COST
I know that cost is an issue with most so a product like the E-switch not a bad alternative to get a cheap micro. But for a little more bling you can get a solid micro. Too bad good things like the KWJA don't last forever, damned economy and business practices. lol
I hope this topic to be helpful and productive for those seeking this info.
Thanks agains for everyone's input
