Joystick Mechanisms
Just a fun-filled list of joystick mounts for easy fact finding.
Seimitsu
Seimitsu sticks to two mounting patterns, for the most part. Either a 50mm square, or 40mm.
They're sometimes sold with a choice of adaptor plate, sometimes there's no choice. Sometimes, for special editions (or their NOBI stick) the adaptor plate has a sticker on it that needs to be removed if the adaptor plate doesn't fit your intended panel.
Generally speaking all their adaptor plates are compatible with the stick mechs, so if you have a 40mm stick, any of their P=40 plates will work.
Their entire catalogue of available plates (in 2023) is available on the Adaptor Plates page.
Seimitsu 40mm Mechs
Most of Seimitsu's sticks are 40mm.
- SELS-70X
- LS-62
- LS-60
- LS-58
- LS-56
- LS-55
Seimitsu 50mm Mechs
- LS-32
- LS-40
- NOBI
SNK
SNK's home consoles used Seimitsu mechs (or clones of them) with a 40mm pattern. Shown below is a mech from a NeoGeo AES joystick (the original and CD sticks used the same mechs). Also shown is Seimitsu's new SELS-70X, which uses the same 40mm mount pattern.
Sanwa
Sanwa uses two mount patterns: either a simple 65mm two-screw attachment, or a square pattern that's much smaller than Seimitsu's, and it's rotated 45 degrees. Instead of having one screw on each diagonal, they're on the vertical and horizontal axes.
Hori
Hori's made many mechs throughout their history. Only one was designed and sold for arcade use: the Hayabusa ( 隼 ). It uses a standard Sanwa mount, but uses a much larger base which may not directly fit a mount made for Sanwa's smaller base. For example, the SNK Super 29 Candy cab's Sanwa plates, or Sanwa's JLF-P-1S.
The Hayabusa shown above includes the mounting plate. It is 36mm from top of plate to bottom of shaft, 78.5mm shaft length.
ASCII
ASCII made many joysticks, and distributed Sega's Dreamcast arcade stick in North America (as Agetech).
CX4J
ASCII were first to market with an optical mechanism, possibly developed with Sanwa, who later released an identical unit called the JLHS-8 FLASH 1. It has two additional wires for Vcc and Ground, to power the LEDs.
It is branded ASCII (and OMRON) with a part number C4XJ.
This mech is compatible with Sanwa JLF mounts and accessories.
