NKK Switches Process Sealed Subminiature Antistatic Toggle B28EB

The B Series is a line of subminiature, sealed antistatic toggle switches designed for low-voltage, low-current logic-level applications. The switches feature a totally sealed body with epoxy-sealed terminals, a carbon-impregnated bushing and support bracket for electrostatic discharge protection, and STC contact mechanism for enhanced reliability. They have a 0.4VA maximum resistive load rating at 28V AC/DC, contact resistance of 50 milliohms maximum, and insulation resistance of 500 megohms minimum. The operating temperature range is -30°C to +85°C. Terminals have a 0.100-inch (2.54mm) spacing conforming to standard PCB grid layout. The series includes options for a 6mm diameter threaded bushing for IP65 panel seal mounting. Mechanical life is 50,000 to 100,000 operations depending on circuit type. The housing is made of glass fiber reinforced polyamide, contacts are gold-plated, and gaskets are nitrile butadiene rubber. Flammability rating UL94V-0 is available.
