Standards & Certifications 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.

C 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 contaminants100 x .100 (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
