NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB25AH-FB

The BB25AH-FB is a subminiature, PCB-mount, antistatic pushbutton from the BB Series, designed for low-voltage logic-level circuits. It features a double-pole, alternate-action circuit with latching mechanism, right-angle PCB terminals, and a white 5.1mm diameter plunger cap. The switch has a sealed construction with carbon-blended polyamide bushing and tin-plated phosphor bronze bracket for ESD protection. Contact resistance is 50 milliohms maximum, insulation resistance is 500 megohms minimum at 500V DC, and dielectric strength is 500V AC for one minute. Nominal operating force is 2.94N. Travel is 2.0mm total. Operating temperature ranges from -30°C to +85°C. The unit has a terminal spacing of 2.54mm x 2.54mm and meets UL94V-0 flammability standard. Mechanical and electrical life is rated at 25,000 operations for alternate action. Dimensions are consistent with the BB Series subminiature form factor, approximately 1/3 the size of Series M switches.
