The Sanwa OBSF-40 is a premium 40mm snap-in pushbutton designed for arcade cabinet builders, MAME enthusiasts, and fightstick modders who demand authentic Japanese arcade performance. Known for its smooth operation, sensitive response, and quiet activation, this yellow button delivers the same quality found in professional arcade machines across Japan.
Ideal for metal control panels with 2-4mm thickness (0.08-0.16"). The OBSF-40's larger 40mm size makes it perfect for admin buttons, service controls, or special function buttons on arcade cabinets. Compatible with Arcade1Up modifications, custom MAME builds, and professional arcade restorations.
Sanwa buttons are the gold standard in arcade hardware, offering shorter throw distance and lighter touch compared to American-style buttons. The snap-in design ensures secure mounting without tools, while the included SW-68 microswitch provides reliable, tournament-grade performance that professional players trust.
