Sanwa and Seimitsu mounting plates

I was digging through my arcade junk boxes and found a total of six different types of joystick mounting plates. To help me remember, and to share with anyone else who cares, I snapped some pics and added descriptions of which plates work with which machines/panels/sticks.

Disclaimers: I do not know the actual part numbers of these plates for ordering, and the names I use may not be official product names. I am not offering any for sale here. This is just a pictorial reference to understand what type/shape of plates are out there for Japanese arcade control panels (Sega/Namco/Konami).



1: Sanwa flat mounting plate which fits my Namco Exceleena square control panel (with four mounting posts welded to the panel). Note: this plate should come with 4 small nuts which go INSIDE the sanwa stick, and 4 small screws. This is used to secure the plate to the stick.

2: Sanwa S-Plate used to mount a Sanwa stick to an original Sega Astro City (type 1) panel. Note: this plate should come with 4 small nuts which go INSIDE the Sanwa stick, and 4 small screws. This is used to secure the plate to the stick.

3: Chinese flat mounting plate (also has 2 holes for Sanwa) which fits my Namco Exeleena square control panel (with four mounting posts welded to the panel). For Sanwa sticks, use the 2 above/below holes, for Chinese sticks, use the 4 holes.

4: Seimitsu flat mounting plate which fits my Namco Exceleena square control panel (with four mounting posts welded to the panel).

5: Seimitsu shallow S-Plate used to mount on an original Sega Astro City (type 2) panel.

6: Seimitsu S-Plate used to mount on an original Sega Astro City (type 1) panel.

For further reference, here are some pics of my panels with various sticks/plates mounted.

*This also fits perfectly on an Astro type 2 panel.

**This is a hack, note the two orange zip ties on the bottom since the holes did not exactly line up.

***No plate needed, as this panel has built in metal mounting points for above/below screws).
