NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB16AH-FB

The BB16AH-FB is a double-pole, right-angle PCB-mount pushbutton in the BB Series, designed for low-voltage, logic-level applications. It features a 5.1mm diameter black cap, a 5.4mm long plunger, and an alternate-action (maintained) circuit with latchdown for audible and tactile feedback. The switch has antistatic protection via a carbon-impregnated bushing and support bracket, with terminals spaced at 2.54mm x 2.54mm to match standard PCB grids. It is rated for 0.4VA maximum at 28V AC/DC, with contact resistance under 50 milliohms and insulation resistance over 500 megohms. Mechanical and electrical life are rated at 25,000 cycles for alternate-action use. Operating temperature ranges from -30°C to +85°C. The sealed housing provides environmental protection, and the body meets UL94V-0 flammability standards. Dimensions include a 6.0mm actuator diameter and a 5.08mm terminal pitch.
