NKK Switches Process Sealed Subminiature Toggle A28AP-GA

The A series is a family of process-sealed subminiature toggle switches designed for low-voltage, logic-level circuits with a maximum resistive load of 0.4VA at 28V AC/DC. The switches feature a totally sealed body, nonshorting contact timing, and a 26° angle of throw. Contact resistance is 50 milliohms maximum, insulation resistance is 500 megohms minimum, and dielectric strength is 500V AC. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, and 50,000 for others; electrical life is 50,000 operations. Operating temperature ranges from -30°C to +85°C. Terminals have a 2.54mm x 2.54mm spacing conforming to standard PCB grids. The case and toggle are made of glass fiber reinforced polyamide, with phosphor bronze contacts gold-plated for reliability. Mounting options include straight, right-angle, and vertical PC terminals. The part number A28AP-GA is not explicitly listed, but the series features apply to all variants.
