NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB26AH-HA

The BB series consists of subminiature, sealed, antistatic pushbuttons designed for logic-level applications with a maximum electrical capacity of 0.4VA at 28V AC/DC. The switches feature a 6mm diameter bushing, 2.54mm x 2.54mm terminal spacing, and are available in momentary and alternate action configurations. The BB26AH-HA variant is a double pole, alternate action switch with right-angle PCB terminals. It has a contact resistance of 50 milliohms maximum, insulation resistance of 500 megohms minimum, and a dielectric strength of 500V AC for one minute. Mechanical and electrical life is rated at 25,000 operations minimum for alternate action. The housing is made of glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated for reliability. Operating temperature ranges from -30°C to +85°C. The design includes an antistatic bushing and support bracket to prevent static discharge. UL94V-0 flammability rating is available. The switch is sealed, enabling wave soldering and automated cleaning.
