NKK Switches Process Sealed Subminiature Pushbutton AB11BB-HA

The AB series is a line of sealed subminiature pushbuttons designed for low-voltage, low-current logic-level circuits, with a subminiature footprint that saves space on PCBs. The switches feature a totally sealed body construction, STC contact mechanism for positive detent actuation and enhanced reliability, and .100" x .100" (2.54mm x .100" (2.54mm) terminal spacing conforming to standard PCB grid layout. Electrical ratings include a maximum capacitive load of 0.4VA at 28V AC/DC, contact resistance of 50 milliohms max, insulation resistance of 500 megohms min, and dielectric strength of 500V AC for one minute. Mechanical and electrical life is rated at 50,000 operations minimum. Nominal operating force is 2.55N, with a total travel of 1.1mm and nonshorting contact timing. Operating temperature ranges from -30°C to +85°C. The series is not UL recognized or CSA certified. Terminals are epoxy sealed or ultrasonically welded for contamination resistance and support wave or manual soldering.
