NKK Switches Process Sealed Subminiature Pushbutton AB25AH-FA

The AB25AH-FA is a subminiature, sealed, double-pole double-throw pushbutton switch designed for logic-level applications. It features a straight right-angle PCB mount with terminal spacing of 2.54 mm x 2.54 mm, conforming to standard board grids. The switch is rated for 0.4 VA maximum at 28 V AC/DC, with contact resistance of 50 milliohms maximum and insulation resistance of 500 megohms minimum. It has a mechanical and electrical life of 50,000 operations, operates within a temperature range of -30°C to +85°C, and uses a nonshorting contact timing mechanism with 1.1 mm total travel. The actuator has a 5.4 mm long black polyacetal plunger and a 7.5 mm diameter white cap. The housing is glass fiber reinforced polyamide with phosphor bronze contacts plated in gold. It is not UL or CSA certified and is intended for low-voltage circuits only.
