NKK Switches Process Sealed Subminiature Antistatic Toggle B12KB-AA

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 to prevent static discharge, and a locking lever option. They have a nominal operating force of 1.47N for momentary and 1.18N for maintained positions for A-type toggles, 50,000 operations minimum electrical life, and a 100,000 operations minimum mechanical life for On-None-On and On-Off-On circuits. Electrical capacity is 0.4VA maximum at 28V AC/DC, with contact resistance under 50 milliohms and insulation resistance over 500 megohms at 500V DC. The operating temperature range is -30°C to +85°C, and the mounting configuration with a 6mm diameter threaded bushing meets IP65. Terminals have 2.54mm x 2.54mm spacing, and the housing is made of glass fiber reinforced polyamide.
