NKK Switches Process Sealed Subminiature Pushbutton AB11AB1-FA

The AB11AB1-FA is a single-pole, double-throw, momentary-on pushbutton in the AB Series, designed for logic-level applications with a sealed subminiature PCB mount. It has a .213" (5.4mm) long black plunger and a .295" (7.5mm) white cap, with right-angle terminals spaced at .100" (2.54mm). Nominal operating force is 2.55N, total travel is .043" (1.1mm), and it operates from -30°C to +85°C. Contact resistance is 50 milliohms max, insulation resistance 500 megohms min at 500V DC, and dielectric strength is 500V AC for one minute. Mechanical and electrical life is 50,000 operations minimum. The STC contact mechanism provides positive detent actuation and enhanced reliability. The body is epoxy sealed, terminals are molded-in for contamination protection, and the housing is glass fiber reinforced polyamide with a polyacetal plunger. No UL or CSA certification is provided.
