Manual Soldering: See Profile B in Supplement section. Automated cleaning. Boot must be on switch during processing. See Cleaning specifications in Supplement section. 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.nkk.com Toggles Series SK Process Sealed Keylocks Rockers Distinctive Characteristics Pushbuttons Sealed body construction plus disposable boot protect contacts and allow automated processing. 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. Rotaries F Keylocks Programmable Illuminated PB Molded-in terminals seal out flux, solvents, and other contaminants. Slides Bifurcated, self-wiping contact mechanism provides unequalled logic-level reliability and smoother, positive detent actuation. Tactiles Crimped bracket legs ensure secure PCB mounting and prevent dislodging during automated wave soldering. Touch Tilt .100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing.
