NKK Switches Process Sealed Subminiature Pushbutton AB11CB

The AB11CB is a subminiature, sealed, single-pole, double-throw pushbutton switch designed for logic-level applications with a 0.4VA maximum resistive load rating at 28V AC/DC. It has a nominal operating force of 2.55N, nonshorting contact timing, a pretravel of 0.7mm, and an overtravel of 0.4mm. The terminal spacing is 2.54mm, conforming to standard PCB grid layout. The plunger is 0.080in (2.03mm) long with a black cap. Contact materials include phosphor bronze with gold plating and brass stationary contacts with gold plating. The housing is glass fiber reinforced polyamide, and the support bracket is tin-plated phosphor bronze. The switch operates from -30°C to +85°C, survives 90-95% humidity for 96 hours at 40°C, and withstands 50G shock and 10-55Hz vibration. Mechanical and electrical life is rated at 50,000 operations. It is not UL or CSA certified.
