SS312SAH4-R NKK Switches

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 ). H 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-D 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.)
