NKK Switches Ultra-Miniature Process Sealed SMT Pushbutton G3B25AB

The G3B25AB is an ultra-miniature, process-sealed surface mount pushbutton switch designed for low-voltage, low-current logic-level circuits. It features a double-pole, double-throw (DPDT) ON-(ON) circuit with gull-wing terminals and upright mounting with bracket. The switch weighs 0.6 gram and has a nominal operating force of 2.0N with a total travel of 1.1mm. It is rated for 50,000 mechanical and electrical operations, with contact resistance of 80 milliohms max and insulation resistance of 500 megohms min. The actuator, case, and base are made of polyphenylene sulfide (UL94V-0), and contacts are phosphor bronze with gold plating. The operating temperature range is -30°C to +85°C. Tape-reel and stick-tube packaging options are available, with tape-reel meeting EIA-481-D standards. Coplanarity is within 0.15mm. The switch is suitable for reflow soldering and automated cleaning.
