Process Sealed Subminiature Pushbuttons Series AB Distinctive Characteristics Subminiature size (1/3 size of Series M switches) saves space on PC boards. Specifically developed for logic-level applications. Totally sealed body construction prevents contact contamination and allows time- and money-saving automated soldering and cleaning. Award-winning STC contact mechanism with benefits unavailable in conventional mechanisms: smoother, positive detent actuation, increased contact stability and unparalleled logic-level reliability. (Additional STC details in Terms & Acronyms; see Supplement section.) Molded-in, epoxy sealed or ultrasonically welded terminals lock out flux, solvents, and other contaminants. .100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing. Matching indicators available and shown at the end of Section M.

The AB Series pushbuttons have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy.
