NKK Switches Process Sealed Subminiature Pushbutton AB11CH

The AB11CH is a single-pole, double-throw, momentary-on subminiature pushbutton designed for logic-level applications, with a sealed, PCB-mount construction. It features a .201" (5.1mm) diameter cap, right-angle terminals, and a .100" x .100" (2.54mm x 2.54mm) terminal spacing that conforms to standard PCB grid layouts. The switch operates with a nominal force of 2.55N, has a travel of 1.1mm, and is rated for 50,000 electrical and mechanical operations. Its contacts are gold-plated phosphor bronze and brass, with a maximum contact resistance of 50 milliohms and insulation resistance of 500 megohms. Operating temperature ranges from -30°C to +85°C. The unit is sized for compact PCBs, with overall dimensions matching the AB11 series: 5.08mm x 5.08mm x 5.08mm. The switch is not UL or CSA certified, and is intended for low-voltage, low-current circuits.
