NKK Switches Process Sealed Subminiature Antistatic Toggle Nkk Switches B28AB

The B Series is a subminiature, sealed, antistatic toggle switch designed for logic-level applications, featuring a carbon-impregnated bushing and support bracket to prevent static discharge. It has a .100" x .100" (2.54mm x 2.54mm) terminal spacing conforming to standard PCB grids. The housing is made of glass fiber reinforced polyamide with epoxy-sealed terminals, and the contacts use an STC mechanism for positive detent actuation and high reliability. The switch operates at up to 0.4VA at 28V AC/DC, with a contact resistance of 50 milliohms maximum and an insulation resistance of 500 megohms minimum. It achieves 100,000 mechanical operations for On-None-On and On-Off-On circuits, and 50,000 electrical operations. Operating temperature ranges from -30°C to +85°C. Locked lever and threaded bushing variants meet IP65 with a 6mm diameter thread. The switch meets UL94V-0 flammability standards but is not UL-recognized or CSA-certified.
