| Process Sealed Keylocks Series SK Distinctive Characteristics Sealed body construction plus disposable boot protect contacts and allow automated processing. Molded-in terminals seal out flux, solvents, and other contaminants. Short body size for space-saving, behind panel dimensions. Detent mechanism, with its spring-operated steel ball, gives crisp, positive action for accurate switch setting. Bifurcated, self-wiping contact mechanism provides unequalled logic-level reliability and smoother, positive detent actuation. Crimped bracket legs ensure secure PCB mounting and prevent dislodging during automated wave soldering. .100" x .100" (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
