NKK Switches Process Sealed Subminiature Rocker A22K1H-DA

The A22K1H-DA is a subminiature sealed rocker switch designed for low-voltage, logic-level circuits. It features a DPDT ON-NONE-ON circuit with a .250" (6.35mm) wide black rocker and right-angle PC terminals. The switch has a contact resistance of 50 milliohms maximum, an insulation resistance of 500 megohms minimum, and a dielectric strength of 500V AC for one minute. It operates reliably for 50,000 electrical cycles and 100,000 mechanical cycles. The actuator requires 1.84N of force, with a 26° throw angle and nonshorting contact timing. The body is constructed of glass fiber reinforced polyamide with nickel-plated brass actuator and gold-plated phosphor bronze contacts. Operating temperature ranges from -30°C to +85°C. The terminal spacing is .100" (2.54mm), conforming to standard PCB grid spacing. The switch is sealed for automated soldering and cleaning, and mounting requires the PCB extension not to exceed .051" (1.3mm) to avoid interfering with rocker movement.
