Official Sanwa arcade buttons, imported directly from Sanwa Denshi Co. Ltd. in Japan.
The Sanwa OSBF-30 are 30mm diameter snap-in arcade buttons. Designed to mount into 2-4mm thick metal panels, we have used them successfully in thicker wooden panels such as the Arcade 1UP. They feature a 'quiet' microswitch (not 'clicky') which is responsive and hard-wearing. They can be connected using spade terminals for quick installation and removal or can be soldered into place.
