The KOWAL™ 1mm oversize actuator is manufactured from hard wearing Nylon and is intended to be used as a replacement actuator on the Sanwa JLF series of joysticks. Once fitted, you will benefit from a shorter throw and faster engagement of your joystick, which will result in improved gameplay. The KOWAL™ 1mm oversize actuator is ideal for fight stick builders and those customers who like modding fight sticks for improved performance. The KOWAL™ 1mm oversize actuator has been tested with square and octagonal restrictor plates and engages the stock switches on the Sanwa JLF series of joysticks consistently.

The KOWAL™ 1mm oversize actuator is compatible with all the Sanwa JLF series of joysticks.

Installing the KOWAL™ 1mm oversize actuator is very straight forward.
1/ Take your JLF series joystick and using a small flat head screwdriver, gently prise off the C Clip on the bottom of the joystick.
2/ Lift off the stock actuator. Replace this with the KOWAL™ 1mm oversize actuator and gently push down.
3/ Using a small pair of pliers, gently grip the C Clip and with a gentle squeeze, the C Clip will snap back into place.

Dead Zone:
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.

    Easier octo gate inputs

    Posted by Jarek on 25th Oct 2021

    Made a huge difference when using octo gate. I used to miss diagonal inputs when doing circular motions a lot. This little thing helps massively and there are no downsides. I thought it would introduce accidental inputs. None of that.

    Kowal 1mm actuator

    Posted by Patrick Waltermann on 14th Aug 2021

    Has improved my inputs significantly and does exactly what it is supposed to. The durability also seems to fit, as there has been no wear and tear so far.

    Not-too-thick and not-too-thin

    Posted by DNIWE on 10th May 2021

    Insalled easily and works well with round or square gate. Dumpens the feel of direction for octagonal gate, since it's wider and doesn't fit into corners.

    Does exactly what it says on the tin!

    Posted by Chris Lewis on 13th Sep 2020

    The effect of this is simply to shorten the thorw of the stick.
    This means it's going to be personal preference of course, and you may find pros and cons depending on the genre of game you're playing... I'm using this in addition to a 4lb spring, and I find it to be extremely responsive and accurate. Much nicer feel than the loose feel of the unmodified JLF.

    Value for money wise, it's a no brainer!! Give it a try

    Actuation Distance

    Posted by LaryIsland on 12th Aug 2020

    The oversized actuator works perfectly in my Hori RAP 4 Kai (with a KOWAL Hayabusa Octopus Gate) to reduce actuation distance. It does exactly what it says on the tin and have found no issues with it so far. 10/10 would recommend
