NKK Switches Process Sealed Subminiature Toggle A12KP-BF

The A Series is a line of process sealed subminiature toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature a totally sealed body, nonshorting contact timing, and STC mechanism for reliable actuation. Terminals are spaced 2.54 mm × 2.54 mm to conform to standard PCB grids. Toggle actuators are made of glass fiber reinforced polyamide (antistatic) or nickel plated brass. Contacts use phosphor bronze and brass with gold plating. Operating temperature ranges from -30°C to +85°C. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits; electrical life is 50,000 operations. Contact resistance is 50 milliohms maximum, insulation resistance 500 megohms minimum, and dielectric strength 500 V AC for one minute. Rated for 0.4 VA maximum at 28 V AC/DC. Wave soldering is recommended. The part number A12KP-BF is not listed, but the series applies to all variants including K toggle types with vertical PC terminals.
