NKK Switches Process Sealed Subminiature Pushbutton AB25AB-HB

The AB25AB-HB is a double-pole, on-on pushbutton switch with a straight PC terminal and bracket mounting style, designed for low-voltage, low-current logic-level circuits. It features a subminiature footprint with 2.54mm x 2.54mm terminal spacing, conforming to standard PCB grid layouts. The switch has a nominal operating force of 2.55N, nonshorting contact timing, and total travel of 1.1mm. It is rated for 50,000 mechanical and electrical operations, with contact resistance ≤50 milliohms and insulation resistance ≥500 megohms at 500V DC. The housing is made of glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated for reliability. Operating temperature ranges from -30°C to +85°C. The unit is sealed for contamination resistance and supports automated soldering and cleaning. It has not been tested for UL or CSA certification.
