NKK Switches Process Sealed Subminiature Rocker A12K1H-DA

The A12K1H-DA is a single-pole, right-angle, snap-top rocker switch designed for logic-level circuits, with a 2.54mm x 2.54mm terminal spacing conforming to standard PCB grid patterns. It features a sealed body, gold-plated phosphor bronze contacts, and a glass fiber reinforced polyamide housing. The switch operates with a nominal force of 1.84N, has a contact resistance of 50 milliohms max, and an insulation resistance of 500 megohms min. It withstands 500V AC for one minute, supports 100,000 mechanical operations for on-none-on circuits, and has an electrical life of 50,000 operations. The operating temperature range is -30°C to +85°C, and the rocker throw angle is 26°. The actuator measures 0.250" (6.35mm) wide. Installation requires no PCB overhang beyond 1.3mm to prevent interference with rocker movement.
