NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB15AB/328-HA

The BB15AB-FA is a subminiature, PCB-mount, antistatic pushbutton switch with single pole, double throw (SPDT) contacts and a bracketed right-angle terminal configuration. It features a momentary circuit with a latchdown mechanism for tactile and audible feedback, a 6mm diameter bushing, and a 5.1mm diameter black plunger cap. The switch is rated for 0.4VA maximum at 28V AC/DC, with a contact resistance of 50 milliohms maximum and an insulation resistance of 500 megohms minimum. Mechanical and electrical life is 50,000 operations for momentary action, and it operates within a temperature range of -30°C to +85°C. The case is sealed and constructed with glass fiber reinforced polyamide, carbon-blended polyamide bushing, and gold-plated phosphor bronze contacts. Terminal spacing is 2.54mm x 2.54mm, conforming to standard PCB grids. The switch meets UL94V-0 flammability standards but is not UL or CSA recognized.
