Sanwa OBS-30A-K 30mm Snap-In Arcade Pushbutton with Micro Switch, Black
Sanwa Denshi arcade components are famous among Japanese arcade enthusiasts and custom fightstick builders. The Sanwa OBS-30A-K is a 30mm snap-in push button featuring a sleek black housing and a built-in micro switch. Compared to standard Sanwa buttons that use the SW-68 switch, this model offers a slightly stronger rebound force and superior durability.
Built for convenient installations, the wiring connects directly from the side, making it an excellent choice when space beneath the mounting plate is limited. The wiring can be configured for either OFF-to-ON or ON-to-OFF operation. When it comes to maintenance, the internal OBS-M-1 switch can be replaced in a single step without taking off the button cap.
This brand new button fits standard 30mm mounting holes with a maximum plate thickness of 3.7mm. For cleaning, stick to a neutral detergent to keep the resin in top shape, as strong alcohol or solvents can cause discoloration and damage to the material.
