NKK Switches Process Sealed Subminiature Pushbutton AB25AV

The AB25AV is a double-pole, vertical-mount, subminiature pushbutton switch designed for logic-level applications, featuring a sealed construction to prevent contamination and support automated soldering and cleaning. It has a terminal spacing of 2.54 mm × 2.54 mm, conforms to standard PCB grid spacing, and operates with a nominal force of 2.55 N. The switch meets an electrical capacity of 0.4 VA maximum at 28 V AC/DC, with contact resistance under 50 milliohms and insulation resistance over 500 megohms at 500 V DC. It supports 50,000 electrical and mechanical operations, with a total travel of 1.1 mm and nonshorting contact timing. Operating temperature ranges from -30°C to +85°C. The actuator is engineered with an award-winning STC contact mechanism for smooth, positive detent actuation and enhanced reliability in low-current circuits.
