The KOWAL™ 1mm oversize actuator is a simple, economical, and non-invasive performance modification for Sanwa JLF joysticks. It replaces the original Sanwa JLF-Series actuator, offering a shorter throw (-1mm), plus faster engage and diagonal (+1.5mm), while retaining the original neutral zone - a critical area that allows the joystick to properly return to center and set up the next direction.
Moves such as Mortal Kombat 9's "Instant Air Gas Blast" for Kabal, or Guilty Gear's X's "In Air Dash" are greatly improved. Other moves such as jump cancel specials (canceling the pre-jump frames of a super jump into a special attack, common with UMVC3) are easier to perform.
In the diagram above: Neutral Zone (area where actuator doesn't touch switches) is indicated in BLUE; Dead Zone (area where actuator presses begins pressing switch) is BLACK; Activation (are where switch is pressing down) is RED. KOWAL™ actuator retains the neutral zone. This allows switches to perform normally.
Beware of actuators that decrease the neutral zone by simply making the entire actuator larger.
It's important to remember that Dead Zone and Neutral Zone are not the same. Actuators cannot use the neutral zone for faster engage because the switch must have this area in order to function properly. The KOWAL™ actuator factors in the neutral zone so that it doesn't block the switches' own plungers. This allows the switches to function normally, enabling the actuator to correctly bounce back to the center upon release, ready for the next directional move.
There are other oversize actuators on the market. However, many of them do not properly factor in the Neutral Zone. Instead, they simply enlarge the entire actuator, cutting off the Neutral Zone and affecting the proper activation of the switches. This messes up the Activation Zone as well, and works against the intended goal of speeding up engage and shortening throw. If you see 1.5mm actuators or larger, keep this in mind -- anything larger than 1mm starts to mess up the proper function of the standard 200gf (operating force) JLF switches. Anything less than 1mm won't shorten engage distance effectively.
The KOWAL™ 1mm actuator is tested on both square and octagonal gates and best used with the stock Omron 200gf switches that come with the Sanwa JLF. It is designed in a lightweight nylon material, and its non-tapered shape allows the actuator to engage switches consistently.
Kowal is the name of a well-respected member on Shoryuken.com forums and elsewhere in the arcade community. He has extensive knowledge of the inner workings of many control devices. Kowal originally introduced the oversized actuator as a performance enhancement for SHMUPs (horizontal or vertical space shooters like Gradius, DoDonPachi, etc.) but was later found to work great with many fighting game titles. With his permission, we introduce the KOWAL™ brand of performance solutions that highlight accuracy and compatibility above all else.
Option bundle the KOWAL™ 1mm oversize actuator with a Sanwa JLF-TP-8YT Joystick, or Sanwa JLF-TP-8Y-SK Joystick (No Plate Installed) for just $3.95!
Easy install and fantastic feel compared to the stock square gate I had. Unknown on Jun 15th 2018
Seriously just what my headline says best investment. Made inputs so much easier. Highly recommend it. It’s just a couple bucks, I say why not and give it a try! Danny on May 28th 2018
Excellent, easy install, does exactly what it promised, stopped eyeing any new sticks because I'm 100% satisfied with my setup right now. 5/5 - Offensive Gaming Offensive Gaming on May 26th 2018
Not a bad upgrade, it made stick movement feel smoother for me. Unknown on Apr 27th 2018
Great product! Reduces the throw of the stick by a significant amount, making execution feel tighter while not losing any feel from the controls or placement of the stick. I have one in all of my active sticks. Brian Luger on Apr 18th 2018
Helps with precision so much. Cleans up unwanted jumps from crouches so much. Dashing feels so much more smooth. Unknown on Apr 6th 2018
I thought Id give it a try and it really did work out. I really do like it and a good deal. Unknown on Mar 31st 2018
First time installing. Sure learned a lot from my mistakes lol. The product works as intended. Unknown on Mar 30th 2018
Unfortunately for me im using an off brand joystick which is decent but really not designed for competitive play. With this the stick certainly feels a little more responsive. Just wish I could use this on a sanwa joystick Unknown on Mar 19th 2018
I have a sanwa JLF and for my personal style of play the improvement was noticeable within about a week
not a magic get good quick fix but really makes it easier to pull off small quarter circles and srk Unknown on Mar 16th 2018
