Totally sealed construction with internal o-ring, with gasket between base and housing, and with insert-molded terminals, gives protection for automated processing techniques. Subminiature size allows high density mounting. Molded-in terminals prevent entry of flux and other contaminants. Crimped bracket legs ensure secure PCB mounting and prevent dislodging during automated wave soldering. Bifurcated, self-wiping contact mechanism provides unequalled logic-level reliability and smoother, positive detent actuation. Detent mechanism, with its spring-operated steel ball, gives distinct feel and crisp actuation for accurate switch setting. .100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
