NKK Switches Process Sealed Subminiature Pushbutton AB11BB-HB

The AB series consists of sealed subminiature pushbuttons designed for low-voltage logic-level circuits, with a subminiature footprint that saves space on PCBs. It features a totally sealed body and STC contact mechanism for positive detent actuation and reliable operation. The switch has a nominal operating force of 2.55N, pretravel of 0.7mm, and overtravel of 0.4mm. It is rated for 50,000 mechanical and electrical operations, with contact resistance below 50 milliohms and insulation resistance above 500 megohms at 500V DC. Operating temperature ranges from -30°C to +85°C. The unit is PCB-mounted with right-angle terminals and an integrated bracket, as indicated by the "H" and "B" designations. Terminals are spaced at 0.100" (2.54mm) to match standard PCB grids. Contacts are gold-plated phosphor bronze, and the case is glass fiber reinforced polyamide.
