NKK Switches Process Sealed Subminiature Antistatic Toggle B12KB-BB

The B Series is a family of subminiature, sealed, antistatic toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature a totally sealed body with epoxy-sealed terminals, a carbon-impregnated bushing and support bracket for ESD protection, and a detachable locking lever option. They have a nominal contact resistance of 50 milliohms maximum, insulation resistance of 500 megohms minimum, and a dielectric strength of 500V AC for one minute. Electrical capacity is 0.4VA maximum at 28V AC/DC, with an operating temperature range of -30°C to +85°C. The switches have 2.54mm x 2.54mm terminal spacing, conforming to standard PCB grids. A threaded bushing option with 6mm diameter meets IP65 for panel seal mounting. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others. Contact timing is nonshorting with a 26° angle of throw.
