The Silencer pads compatible with the recent Hori Hayabusa low-profile matte version, but will require cutting off the side tabs. This is similar to Seimitsu PS-15 low profile pushbuttons. Additionally customers have reported compatibility with Samducksa 201 Futaba and 202 MX pushbuttons.
In November 2012, one of the highest voted ideas in our product suggestion forum was creating silent foam washers. This would provide an alternative to Sanwa's ground-breaking, but limited silent button lineup of OBSFS pushbuttons. Imagine having the ability to silence Sanwa OBSN screwbuttons, or the more recent translucent OBSC pushbuttons.
Now imagine the same for Seimitsu.
Available now is Silencer - a 1mm foam washer shaped to fit in both Sanwa and Seimitsu 30mm pushbuttons. Suggested by you, and tested over several months for performance and durability.
Silencer is a 1mm foam washer that conforms to the internal housing of Sanwa and Seimitsu's 30mm pushbutton lineup. It also utilizes small "tabs" at each end of the washer, which additionally absorb the sharp sound created as the pushbutton plunger's tab meets the rim. Sanwa and Seimitsu - for copyright purposes - deliberately orient their plunger tabs differently from one another. Silencer's tabs can be oriented horizontally or vertically for Sanwa or Seimitsu's unique housing. For Sanwa OBSF, OBSN, OBSC and Seimitsu PS-15 pushbuttons, Silencer's tabs can be snipped off without affecting its ability to reduce noise.
Silencer's foam material was chosen for the closest match to Sanwa's original foam washers. For increased durability, an incredibly thin and flexible plastic film was placed on one side.
installing the Silencer foam pads into a Sanwa or Seimitsu pushbutton is straightforward. Place the washer - plastic film side down - into the button housing. Align the small tabs so that they stick out of the holes on each side of the housing. For Seimitsu PS-15 low profile pushbuttons, snip the tabs off with scissors and place into the housing.
The objective of Silencer is to provide an alternative washer for Sanwa and Seimitsu pushbuttons that effectively reduces noise, but also matches the actuation ability and natural feel in Sanwa's OBSFS offering. To do this, we sent prototypes of the washer - originally in clear silicone and later foam - to a group of dedicated testers. Over several months, we learned that foam was more effective in matching Sanwa's original washer and absorbing shock while matching the actuation of Sanwa's own product. We also learned that "springiness" and "mushiness" was an undesired factor in other washers - first with our silicone prototypes, and later with competing solutions.
Further, we performed blind tests with individuals and groups, who assumed that Sanwa's OBSFS pushbuttons were installed. The washers were taken to tournaments in Philadelphia and utilized in joysticks swapped amongst players during the events. Those using Silencers indirectly reported no differences in feel to our testers; they didn't feel "springy" or"mushy", and were able to tap away normals, links and combos as they always did.
Finally, we performed tests in Seimitsu's PS-14 K and KN series of pushbuttons. The KN was most compatible due to its internal housing; Silencers proved effective for both in muffling sound while not restricting their unique feel. Though we couldn't perform blind tests, players that did use them were quite pleased that pads were designed for Seimitsu.
I swear, I was skeptical about what these pads would do or how much they would dampen the noise of my button presses late into the night...but damn, these things are magic. The clickety-clacks are just mushy presses now, and I'm super impressed. Thank you! Titus on Aug 10th 2023
I know sound is the most advertised benefit to these, but the press down feel is a lot nicer now. Gets rid of the plastic on plastic feel, without being too mushy Unknown on May 14th 2023
just bought a replacement set of these silencers, i got my first set a few years ago and they held up to a ton of abuse. they work great on hori hayabusa buttons after cutting off the tabs, no issues with input reg and a massive reduction in volume. i also got a spare one to fit in the 24mm start button with more meticulous trimming.

Worth the small extra cost to have such an amazing feeling and quiet button! Milo on Jun 30th 2022
I can't imagine buttons without these...and don't want to. Unknown on Jun 12th 2022
it works but a little bit noticeable difference. tried it only on Crowns. PS wish theres one for 24s Cappox on Nov 7th 2021
I have purchased these washers several times hoping that they would be a solution to my clicky buttons on my fightsticks, but they aren't. Not entirely.
They do silence you buttons when installed but with the price of have them not register in games 75% of the time. The buttons also feel more stiff and restraint, often having to resort to pushing them harder, and even that doesn't as stated before with the registration issues.
Just save your money towards the silenced SANWA buttons. Those mare much better and built to work. Don't even bother with these washers. Unknown on Apr 10th 2021
Installed these in my Sanwa buttons.
For two bucks, these are easy to install, make the buttons noticeably quieter, and in my opinion, give better feedback when the plunger bottoms out. Buriki One on Jan 30th 2021
Easy way to turn any button silent Unknown on Aug 7th 2020
Originally I bought these for my Sanwa OBSF buttons, but to my surprise this silencer fits Crown 202 screw in buttons perfectly too! Michael H on Jun 18th 2020
