NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB25AP-HC

The BB25AP-HC is a double pole, right angle PCB mount, momentary or alternate action pushbutton from the BB Series, designed for low-voltage, low-current logic-level circuits. It features a 6mm diameter bushing, 2.54mm x 2.54mm terminal spacing, and an antistatic carbon-impregnated bushing and support bracket to prevent static discharge. The switch has a maximum contact resistance of 50 milliohms, insulation resistance of 500 megohms minimum at 500V DC, and dielectric strength of 500V AC for one minute. Mechanical and electrical life is rated at 50,000 operations for momentary and 25,000 for alternate action. The actuator travel is 0.7mm pretravel and 0.4mm overtravel for momentary mode, or 1.0mm for both pretravel and overtravel in alternate action. Operating temperature ranges from -30°C to +85°C. The housing is made of glass fiber reinforced polyamide, with gold-plated phosphor bronze contacts and terminals. The switch is sealed to prevent contamination and meets UL94V-0 flammability standards.
