NKK Switches Process Sealed Subminiature Pushbutton AB11AV1

The AB11AV1 is a single-pole, double-throw, vertical PCB-mount pushbutton in the AB Series of sealed subminiature switches designed for logic-level applications. It features a 0.4VA maximum contact rating, nonshorting contact timing, and a nominal operating force of 2.55N. The switch has a pretravel of 0.7mm and total travel of 1.1mm, with terminals spaced at 2.54mm x 2.54mm to conform to standard PCB grids. The housing is glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated for reliability. It operates from -30°C to +85°C and withstands 90-95% humidity at 40°C for 96 hours. Mechanical and electrical life is rated at 50,000 operations minimum. The STC contact mechanism provides positive detent actuation and enhanced stability. Soldering is recommended via wave or manual methods as per supplement profiles.
