NKK Switches Process Sealed Subminiature Pushbutton AB25AV-FB

The AB25AV-FB is a subminiature, sealed, double-pole, single-throw pushbutton switch designed for logic-level applications. It features a vertical PCB mount with an inline bracket, 0.100" (2.54mm) terminal spacing, and a 0.201" (5.1mm) diameter white cap. The switch has a nominal operating force of 2.55N, nonshorting contact timing, and total travel of 0.043" (1.1mm). It supports a maximum resistive load of 0.4VA at 28V AC/DC, with contact resistance of 50 milliohms maximum and insulation resistance of 500 megohms minimum. The unit is rated for 50,000 electrical and mechanical operations, operates from -30°C to +85°C, and is suitable for wave soldering. Its sealed construction prevents contamination and supports automated cleaning. The STC contact mechanism ensures smooth detent actuation and high reliability in low-current circuits.
