| Ultra-Miniature SMT Slides Series SS3 Distinctive Characteristics Compact dimensions and low profile allow high density mounting and close stacking of PC boards. Crisp actuation positively indicates circuit status. Heat resistant resin allows vapor phase and infrared convection reflow soldering. Award-winning STC mechanism with benefits unavailable in conventional mechanisms: smoother, positive detent actuation, increased contact stability, and unparalleled logic-level reliability. (Additional STC details in Terms and Acronyms in the Supplement section.) Insert molded terminals lock out flux, solvents, and other contaminants. Metric terminal spacing for standard PC board grid (2.0mm x 2.0mm ). Gull-wing terminals provide mechanical stability during soldering and simplified solder joint inspection. Packaged in tape-reel or partitioned tray. Tape-reel packaging meets EIA-481-2 Standard. 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 Profile A in Supplement section. Manual Soldering: See Profile A in Supplement section. These devices are not process sealed. Standards & Certifications Flammability Standards: UL Recognition or CSA Certification: UL 94V-0 rated housing & base The SS3 Series slides 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.
