What do you mean?
So regular Sanwas are pretty easy to accidentally hit, for start/select/home which of these would be most appropriate?
sounds lIke the obs-a/b?
Yeah, for that role (contextual/menu buttons), the OBS-A or OBS-B would be a good choice. As action buttons, however, I’d take RGs any day.
Hey @skaloola , I haven’t kicked off my build yet (still just getting parts together), but I didn’t get any OBS-24A or OBS-24B buttons because I was afraid I would have fitment issues inside my stick with all those larger microswitches… also the added $$$ for buttons not used that often.
Also x2, I don’t think they make OBSN-24 buttons with RG switches 
Doesn’t a company make a sunken in 24mm button? unless the pics I’ve seen a while ago are people that modded the button so it’s harder to hit?
Yeah it was the spring button mod
Also depends where are these buttons located.
Sides or rear are preferable to the top panel where your 6 or 8 fire/punch/kick buttons are.
Use some wire cutters to clip some stock JLF or other light tension spring of approximate size in half and put the spring under the plunger and around the switch. The added tension makes it much harder to accidently hit. Alternatively, I have seen people run system buttons sans plunger so you have to press the switch inside the button body. Not as pretty, but effective.
If you have a few JLF springs left over you could put them in your button. They’ll be pretty stiff to press afterwards, and would be a cheaper solution than OBS-As
so I just received my huge order from akishop. and was trying out different button / switch combos.
hori kuros can hold the obs-m switch housing. Not very snug, but stable. I haven’t drilled them out yet so haven’t tried any switches besides what it comes with, but this combo turns the kuros from “meh” into awesome.
I’m sure I’m not the first to try this, but i hadnt seen any posts suggesting it so wanted to share
I’ve tried OBS-M in other buttons besides Sanwa. They all pretty much feel the same at that point.
well if you say so, then i guess it’s all in my head.
in any case, i definitely prefer the feel and aesthetics of the smaller rim / larger plunger of the kuro compared to the sanwas.
I must be the only guy here who doesn’t care for the OBSF-30RGs. They fit in my TE fine, and they were fun to press by themselves, but actually playing with them was another matter. With fighting games especially, pressing a button was an “event” rather than the very next step up from a thought. And for shmups, well, I don’t want to spend too much energy holding down a button to laser or rapid fire.
I’m actually using stock Mad Catz buttons from an SF4 SE stick and I’m pretty happy with them. I might swap those out for Kuros, but I’m really waiting for the next sale at Focus Attack so I can get those neato Seimitsu PS-14-K buttons with Sanwa SW-68 microswitches.
Love the feel of the OBS-30B’s
Wasn’t BLOWN AWAY by the OBSN-30RG’s, so now they’re for sale in the trading outlet [<link>](WTT: Lots of sticks / parts / & misc’s added | WTB: MAS and Diamond VLX arcadesticks
And @Moonchilde you were right about both of these buttons fitting in the HRAP T5 unmodded.
That thing’s deep enough to fit iL Short Barrel & WICO Perfect360 buttons!!!
Screw-in RGs feel different than the snap-ins in some panels, at least in my experience.
If they just fit, the pressure from the panel can affect the action of the button.
I had some screw-ins in an old stick and those things were PURE SEX. The buttons came in an arcade panel I scooped off eBay and were probably 5+ years old easy before I ever got them. Wish I had held onto them.
edit: like everything else, I wouldn’t be surprised if the build quality of the RGs was better back then. They didn’t feel anything like the ones I have now 
not just RG sanwas. the typical obsn sanwas feel nicer in my opinion than the obsf’s. its probably due to what @eczangief said. also highly reusable.
RG’s are not for everyone i guess, i still encourage people to try them out… now if only sanwa would make them in black or white orz. ill take dark hai RG’s even
Screw in buttons have a more solid design over their snap in counterparts. The barrels have less of that “hollow” feeling that snap ins do. The barrels also get a little more “thick” because of the threading.
Does the Sanwa RG G1 switch fit in any other button?
Not really, there was a Seimitsu version of the same button but they are discontinued.
RG switches can fit in some large switch Seimitsu buttons with these:

So called “RS-SG” (sanwa catalog ref) , relabeled Sanwa switches for OBSF-30RG & OBSF-40RG buttons are really OMRON B2R-G1 reed switches (“G1” printed on the case), if anyone is interested .
Apparently the Seimitsu discontinued buttons with the same omron switch were PS14-GX , and PS-14GXN (both opaque and clear cap covered plunger). They’ve been discussed here before on SRK.
according to a japanese site, the specs are the following :
-actuation distance : 1.57mm
-bottom out : 2.64mm
-force needed to depress the plunger : >= 35.3gf
-actuation force : 50gf
-for to bottom out: 61gf
used in HORI RAP SE before.

edit: Sanwa also made OBSL-30RG, screw-in 30mm buttons, in 6 opaque color variations (including black) . Pic links on SRK are dead so here it is:
OBSL-30RG had unusual bodies for screw-in buttons at the time as the threaded part extended lower around the reed switch in order to accomodate to extra thick control panels ( e.g. wood ) unlike the normal sized threaded part on the OBSN-30RG screw-in, also discontinued , and which also sported the same Omron reed switch.

There were also NAMCO 28mm buttons with an Omron B2R-G1 switch, there’s an article in Erwin’s blog showing a comparison with Sanwa OBSF-30RG and Seimitsu PS-14-GX :
