NKK Switches Process Sealed Subminiature Antistatic Toggle B28AP-GB

The B series is a family of sealed subminiature antistatic toggle switches designed for low-voltage, low-current logic-level circuits. It features a totally sealed body with epoxy-sealed terminals, carbon-impregnated bushing, and a support bracket to prevent static discharge. The switches have 0.4VA maximum contact capacity at 28V AC/DC, 50 milliohms maximum contact resistance, and operate from -30°C to +85°C. Terminal spacing is 2.54mm x 2.54mm, conforming to standard PCB grid spacing. The A1 actuator variant includes a threaded bushing with 6mm diameter for panel seal mounting, meeting IP65 of IEC 60529. Mechanical life is 100,000 operations for ON-NONE-ON and ON-OFF-ON circuits. All models use phosphor bronze contacts with gold plating and a nonshorting contact timing mechanism. The flammability rating is UL94V-0.
