NKK Switches Process Sealed Subminiature Toggle A22HP

The A Series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level applications. The switches feature a totally sealed body to prevent contamination and support automated soldering and cleaning. They have a 26° angle of throw, nonshorting contact timing, and operate with a nominal force of 1.18N to 2.73N depending on toggle size. Contact resistance is 50 milliohms maximum, insulation resistance is 500 megohms minimum at 500V DC, and dielectric strength is 500V AC between contacts and case. Electrical life is rated at 50,000 operations, with mechanical life up to 100,000 for On-None-On and On-Off-On circuits. Operating temperature ranges from -30°C to +85°C. Terminals have a 2.54mm x 2.54mm spacing conforming to standard PCB grid patterns. The case and toggle are made of glass fiber reinforced polyamide, with phosphor bronze contacts plated in gold. The series is not UL or CSA certified.
