NKK Switches Process Sealed Subminiature Pushbutton AB15AB

The AB15AB is a subminiature, sealed, PCB-mount pushbutton switch designed for logic-level applications, with a subminiature footprint saving board space. It features a double-pole, normally-open contact configuration with straight PC terminals and a support bracket. The switch has a nominal operating force of 2.55N, a total travel of 1.1mm, and a contact resistance of 50 milliohms maximum. It operates reliably at 0.4VA maximum under 28V AC/DC, with an electrical and mechanical life of 50,000 operations. Terminals are spaced at 2.54mm × 2.54mm to match standard PCB grids. The housing is made of glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated for durability. It is rated for operation from -30°C to +85°C and withstands vibration up to 55Hz and shock up to 50G. The STC contact mechanism provides smooth, positive detent actuation and enhanced reliability in low-current circuits.
