Ultra-Miniature Process Sealed SMT Pushbuttons Series G3B Distinctive Characteristics Ultra-miniature size allows high density mounting, and extremely light weight of 0.6 gram makes these switches ideal for handheld equipment. Tape-reel and stick-tube packaging allow rapid automated placement of surface mount devices. Tape-reel packaging meets EIA-481-2 Standard. Heat resistant resin used for housing, base, and plunger allows vapor phase and infrared convection reflow soldering. Combination of design features achieves total seal and allows automated processing techniques, including flux cleaning procedures: one-piece bushing and housing, rubber seals surrounding actuator and base, epoxy at joint of case and base, and molded-in, epoxy-sealed terminals. 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.) Gull-wing terminals provide mechanical stability during soldering and simplified solder joint inspection. Coplanarity: all considered surfaces must lie between two parallel planes that are a maximum distance apart of .0059” (0.15mm). (Additional coplanarity details in Terms and Acronyms in the Supplement section.)

See specifications in Terms & Acronyms in Supplement section. Reflow Soldering Recommended. See Profile B in Supplement section. Manual Soldering: See Profile B in Supplement section. Automated cleaning. See Cleaning specifications in Supplement section. The G3B 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.
