Research Notes
1. Overview
The OBSC-30 is Sanwa's 30 mm clear/translucent snap-in pushbutton — the OBSF-30 mechanism (built-in Sanwa microswitch, snap-in, convex) with a transparent/translucent plunger (the 'C' denotes clear). Used where a see-through look, colored-transparent aesthetic, or DIY LED-lit build is desired. Standard 30 mm main-action size.
2. Technical Specifications & Compatibility
See the structured specs on this page (diameter, mounting, plunger/finish, microswitch). These are standard arcade-button form factors — confirm the panel cutout (30 mm / 24 mm / 18 mm as applicable) and the snap-in vs screw-in mount for your panel thickness before ordering.
