Ultra-Miniature SMT Slides
Series SS3
Toggles
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-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.)
