See Profile A in Supplement section. Manual Soldering: See Profile A in Supplement section. Cleaning: Automated cleaning. See Cleaning specifications in Supplement section. Standards & Certifications The SK Series devices 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. www.nkkswitches.com F15 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers TogglesSeries SK Antistatic Process Sealed Keylocks Distinctive Characteristics Housing and bushing of high insulating material withstands over 15 kilovolts of electrostatic discharge, thus providing antistatic protection. 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. F 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 setting100 x .100 (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
