NKK Switches Process Sealed Subminiature Pushbutton AB11AP-FB

The AB Series is a family of sealed subminiature pushbuttons designed for low-voltage, low-current logic-level applications. The switches feature a .100" x .100" (2.54mm x 2.54mm) terminal spacing compatible with standard PCB grids. The AB11 model is a single-pole, double-throw switch without a terminal 2 and has straight PC terminals. Electrical capacity is 0.4VA maximum at 28V AC/DC, with contact resistance under 50 milliohms and insulation resistance over 500 megohms at 500V DC. The mechanism provides nonshorting contact timing, 50,000 operations minimum, and a nominal operating force of 2.55N. Total travel is .043" (1.1mm). The housing is glass fiber reinforced polyamide, with gold-plated phosphor bronze contacts. Operating temperature ranges from -30°C to +85°C. No UL or CSA certification is claimed. The STC contact mechanism delivers positive detent actuation and enhanced logic-level reliability.
