Kowal 1mm Oversize Actuator for Sanwa JLF Series Joystick

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.

Size Matters

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.

Compatibility, Design and Origin of the KOWAL™ Actuator

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.
