NKK Switches A12AH Process Sealed Toggle Switch

The A series process-sealed sub-miniature toggle switch features a completely sealed body construction that prevents contact contamination and enables efficient automated soldering and cleaning. Equipped with the STC contact mechanism, it offers smoother, positive detent actuation, enhanced contact stability, and superior logic-level reliability compared to conventional switches. The switch is available with molded-in, epoxy-sealed, or ultrasonically welded terminals to resist flux, solvents, and other contaminants. Specifically designed for logic-level applications, this compact switch saves space on printed circuit boards with a 2.54 x 2.54 mm terminal spacing that conforms to standard PCB grid dimensions. An antistatic toggle option is available to dissipate electrostatic discharges, and matching indicator lights can be supplied for ease of use.
