PS-14-D MICROSWITCH is the Seimitsu microswitch that’s swappable with the Sanwa SW-68.
PS-14-G microswitches are NOT cross-compatible with the SW-68! Take it from someone who has flipped these microswitches…
The PS-14-D Microswitch is what these Seimitu buttons use –
PS-14-P “Pearl” button (out of production, basically unavailable now; most comfortable stock Seimitsu buttons I’ve used; the only 30mm Seimitsu buttons that felt good to me with the stock microswitch)
PS-15, the thinnest 30mm Japanese-style buttons on the market ( <= this is the button I switched micros on; much more comfortable to use with the SW-68!)
PS-14-D/24mm plug-in buttons, and more…
To repeat, any button that uses the PS-14-D microswitch is cross-compatible with the SW-68. I wouldn’t bother with modding the Pearl buttons (if they were available at any rate) but the other 30mm’s can be swapped out micro-wise very readily. Likewise, Rollie pushbuttons and the newer Hori Kuro buttons are cross-compatible with SW-68 microswitches.
I get tired of repeating this stuff so just go to Akihabarashop’s homepage ( http://akihabarashop.jp/ ) and look under “Arcade”, scroll down to “Buttons”. There is a pull-down menu next to the pictures of the joysticks and buttons.
Look through the pulldown’s and compare the microswitch the buttons use. There are probably slightly more than half the Seimitsu pushbutton designs that use the PS-14-D microswitch – all the 24mm buttons, plug-in Skeletons (PS-14-K), and what I listed above use the PS-14-D micro. Every other Seimitsu button uses the PS-14-G (larger) microswitch.
With Seimitsu, you have to be very careful with what you buy or plan to mod. There are two microswitches and what makes the situation even more confusing is how Seimitsu names its parts.
There are PS-14-D microswitches as well as PS-14-D buttons!
You can’t go by the “PS-14” prefix because Seimitsu uses all kinds of Japanese suffixes to differentiate among the buttons… EXAMPLE: there are two styles of 30mm “Skeleton”/transparent buttons that Seimitsu makes. The original is the PS-14-K plug-in that uses the PS-14-D microswitch. What that “K” in PS-14-K means, I couldn’t tell you. (It might be an abbreviation for the Japanese word for “transparent”.) However, the other 30mm “Skeleton” button is the PS-14-K-N which uses the larger PS-14-G microswitch. In that case, I can assure you that the “-N” suffix probably stands for “screw in” or Japanese words to that effect since every Seimitsu screw-in button (regardless of its microswitch) uses the “-N” suffix/modifier.
Again, refer to what Akihabarashop has listed online. You can’t go wrong with their product listing.
Why Seimitsu has two microswitches in production, I wouldn’t know… The company is inexplicable for a lot of its product offerings!
Sanwa makes slightly more sense!
