NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB26AV-FA

The BB26AV-FA is a subminiature, sealed, antistatic pushbutton switch designed for low-voltage, logic-level applications. It features a double-pole, alternate-action circuit with a vertical PCB mount and a black 5.1mm diameter plunger cap. The switch has a terminal spacing of 2.54mm, conforms to standard PCB grids, and provides visible, audible, and tactile latchdown feedback. It operates with a nominal force of 2.94N and has a mechanical and electrical life of 25,000 cycles. The actuator travel is 2.0mm, and the housing is constructed from glass fiber reinforced polyamide with a carbon-blended polyamide bushing for ESD protection. The device is rated for operation between -30°C and +85°C, withstands 500V AC dielectric strength, and meets UL94V-0 flammability standards. Its sealed construction resists contamination and supports wave soldering and automated cleaning.
