Manual Soldering: See Profile B in Supplement section. Cleaning: Automated cleaning. Boot must be on switch during processing. See Cleaning specifications in Supplement section. Standards & Certifications These 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 F19 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers TogglesSeries SK Process Sealed Keylocks 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 F 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 soldering100 x .100 (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
