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!
The timing has become noticeably quicker after adding this, I also have a 4lb spring in there so that one stick just became a lot more fun.
I also got the octopus for another stick and mad I didn't order 2 at the same time so now the vlx is in the corner until I make another order. Tone on Mar 17th 2016
I bought this and the KOWAL Hayabusa Octopus Octo Gate and this has DRASTICALLY improved my execution. If you've got the Hayabusa, I can't recommend enough picking both of these up at the same time. Codi on Mar 11th 2016
You will immediately notice an improvement in complex joystick executions. Unknown on Mar 10th 2016
This mod is for people who demand the fastest and most precise reactions. If you're not precise you can end up accidentally inputting jump or other inputs but if you're precise and demand the fastest of responses, this will help you reach those ends.
This is great for minimizing movement on the stick and, as a result, making your inputs that much faster. Jon on Mar 5th 2016
I love the kowal 1mm actuator. Combines with the 2lb spring it gave me a tighter and quicker response to executing my moves.
Personal cons: I could not it to work with my hayabusa. For some reason it get stuck when moving. Certain directions worked fine but to other sides it would get stuck. Stefnhawkn on Feb 3rd 2016
It is the same quality as a the rest of my sanwa stick on my razer atrox. its slightly thicker than the stock one which reduced the throw to make my shmup games more responsive sean on Feb 1st 2016
I put octo gates on my cab years ago but one thing always bugged me about them, they extend the horizontal and vertical throw to the gate. If you think of the standard square gate, the octo gate applies that corner distance to the x/y axes as well. Anyway the Kowal actuator pulls the distance back in and makes for a much tighter stick, it's really nice if the openness of the octo gate vs square bugs you.
There's one other side effect I noticed as well, the stick feels slightly tighter. I'm not sure if the Kowal is a little taller where the spring meets, or if it's something with the switch activation shape difference or what, but whatever it is the stick feels tighter as a result. It's a really subtle change but I like it. Unknown on Dec 11th 2015
I bundled this with the 2lb spring mod, and immediately noticed the difference in tension and responsiveness, when compared to the stock Sanwa JLF setup I had been using for years. This actuator is an excellent addition to any stick, but be warned it shortens the throw of your joystick considerably, and will almost certainly take a moment of "getting used to." Overall, it kills the unnecessary dead-space found in the stock Sanwa JLF, and promotes more precise and deliberate inputs. Unknown on Oct 13th 2015
I think these actuator should be standard on all sanwa but maybe not everyone likes the shorter throw. Overall a great add on. Move execution are improved by far. Will be buying a few more as i have 5 arcade sticks. Hear me out but I think the material should be something a bit more durable as these will wear out. Unknown on Sep 29th 2015
This is a great product. Very well made. Bought for shmups but feel like it's made an improvement on anything I've tried. Must have for a JLF Mike M. on Sep 14th 2015
