NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB15AB-HB

The BB15AB-HB is a double-pole, alternate action, subminiature pushbutton in the BB Series, featuring a right-angle PCB terminal configuration with a 5.1mm diameter black cap and a 5.4mm long plunger. It has a sealed body construction, antistatic bushing and support bracket, and is designed for low-voltage, logic-level circuits. The switch operates with a nominal force of 2.94N, offers nonshorting contact timing, and has a total travel of 2.0mm. Terminal spacing conforms to 2.54mm x 2.54mm(PCB grid standard). It meets UL94V-0 flammability rating, operates from -30°C to +85°C, and supports 25,000 electrical and mechanical operations in alternate action mode. Contact resistance is 50 milliohms maximum, with 500 megohms minimum insulation resistance at 500V DC and dielectric strength of 500V AC for one minute. Materials include gold-plated phosphor bronze contacts and glass fiber reinforced polyamide housing.
