OBSC-24

1. Overview

The Sanwa Denshi OBSC-24 is a 24 mm clear (transparent) arcade pushbutton from Sanwa's OBS-series — the 24 mm size is Sanwa's standard for start/option buttons (with the 30 mm size used for the main action buttons). Clear/translucent plungers are chosen so an LED behind the button can shine through. Like the rest of the Sanwa OBS line it uses Sanwa's own SW-68 non-clicking microswitch with .110" quick-connect tabs and is prized for its light, responsive, quiet feel.

2. User Sentiment

Sanwa is the benchmark brand for Japanese-style arcade buttons; fight-stick and cabinet builders praise the smooth, light, low-noise action and the quality microswitch. The 24 mm OBSC/OBSF buttons are the go-to for Start/Select on custom sticks and cabinets. Clear versions are popular for LED backlighting and custom artwork inserts. The usual care is matching the mounting style (snap-in vs screw-in) to the panel and confirming the 24 mm cutout.

3. Real-World Applications

Start, coin, and option buttons on Japanese arcade cabinets, fight sticks, and hitbox controllers; 24 mm auxiliary buttons alongside 30 mm main buttons. Clear body suits LED-lit setups (e.g. lit start buttons).
