NKK Switches Process Sealed Subminiature Pushbutton AB11AP-HA

The AB11AP-HA is a single-pole, double-throw, right-angle PCB-mount pushbutton in the AB Series, designed for low-voltage, logic-level applications. It has a subminiature form factor with 2.54 mm terminal spacing, conforming to standard PCB grid patterns. The switch features a totally sealed body, a phosphor bronze contact with gold plating, and a polyacetal plunger. It operates at 0.4VA maximum under 28V AC/DC, with a nominal operating force of 2.55N, 50,000-cycle electrical and mechanical life, and contact resistance of 50 milliohms maximum. The device is rated for operation from -30°C to +85°C and withstands 50G shock and 1.5mm vibration amplitude. Soldering is recommended via wave or manual processes per specified profiles. The STC contact mechanism provides positive detent actuation and enhanced logic-level reliability. The part is not UL or CSA certified.
