NKK Switches Process Sealed Subminiature Rocker A18K1B1-EA

The A series is a family of sealed subminiature rocker switches designed for low-voltage, low-current logic-level applications. The switches feature a glass fiber reinforced polyamide housing, phosphor bronze contacts with gold plating, and brass terminals with gold plating. They have a contact resistance of 50 milliohms maximum, insulation resistance of 500 megohms minimum at 500V DC, and dielectric strength of 500V AC for one minute. The nominal operating force is 2.73N for momentary and 1.84N for maintained types, with a 26° angle of throw and nonshorting contact timing. Electrical life is rated at 50,000 operations minimum. The operating temperature range is -30°C to +85°C, and the switches are suitable for wave or manual soldering. Terminal spacing is 2.54mm x 2.54mm, conforming to standard PCB grid patterns. The switches are not UL recognized or CSA certified.
