NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB15AB/328

The BB15AB is a subminiature, sealed, antistatic pushbutton with SPDT circuit, right-angle PCB terminals with bracket, and a black 5.1mm diameter plunger cap. It offers momentary or alternate action with latchdown, providing tactile and audible feedback. The switch has 2.54mm x 2.54mm terminal spacing and operates at 0.4VA maximum. Contact resistance is 50 milliohms max, insulation resistance 500 megohms min, and dielectric strength 500V AC for 1 minute. Mechanical and electrical life is 50,000 operations for momentary or 25,000 for alternate action. Nominal operating force is 2.55N (momentary) or 2.94N (alternate). Travel is 1.1mm or 2.0mm respectively. Operating temperature ranges from -30°C to +85°C. Housing is glass fiber reinforced polyamide; contacts are gold-plated phosphor bronze. ESD protection is integrated via a carbon-impregnated bushing and bracket. UL94V-0 flammability rating applies.
