NKK Switches Process Sealed Subminiature Antistatic Pushbutton BB26AP-FA

The BB26AP-FA is a subminiature, antistatic, PCB-mount pushbutton from the BB Series, designed for low-voltage, low-current logic-level circuits. It features a double-pole, alternate-action circuit with latchdown for audible and tactile feedback, and right-angle PC terminals with a 0.100" x 0.100" spacing. The switch has a 6mm diameter bushing, a polyacetal plunger, and a sealed construction that prevents contamination. Contacts are gold-plated phosphor bronze and copper alloy, with a contact resistance of 50 milliohms maximum and insulation resistance of 500 megohms minimum. The operating force is 2.94N, with a total travel of 2.0mm. Electrical and mechanical life is rated at 25,000 cycles. The unit operates from -30°C to +85°C and meets UL94V-0 flammability standards. Its dimensions conform to standard PCB layouts.
