NKK Switches Process Sealed Subminiature Toggle A22KB-BB

The A series is a family of sealed subminiature toggle switches designed for low-voltage, low-current logic-level applications. All variants feature a totally sealed body, .100" x .100" (2.54mm x 2.54mm) terminal spacing, and a 26° angle of throw. Electrical ratings include a maximum resistive load of 0.4VA at 28V AC/DC, 50 milliohms maximum contact resistance, and 500V AC dielectric strength. Mechanical life is 100,000 operations for On-None-On and On-Off-On circuits, 50,000 for others, with an electrical life of 50,000 operations. Operating temperature ranges from -30°C to +85°C. The case and toggle are made of glass fiber reinforced polyamide; contacts use phosphor bronze with gold plating. The part number A22KB-BB is not explicitly listed, but the series supports double-pole, right-angle PCB terminals and snap-top toggles, confirming this variant falls within the documented series. No UL or CSA certifications are cited.
