0.4VA Logic Level; Process Sealed, PCB MountWashable Through-hole Mount Ultra-miniaturesUltra-miniature size allows high-density mounting, and extreme light weight (0.25 grams) makes these switches ideal for handheld equipment. Fully sealed body construction prevents contact contamination, and allows time and money-saving automated soldering and washing. Award-winning STC contact mechanism offers benefits unavailable in conventional mechanisms: smooth, positive detent actuation, increased contact stability, and unparalleled logic-level reliability. Tape-reel and stick-tube packaging allow rapid automated placement of surface mount devices. Heat-resistant resin used for housing, base, and actuator of SMD allows vapor-phase and infrared reflow soldering. Molded-in, epoxy sealed terminals lock out flux, solvents, and other contaminants. .100" X .100" terminal spacing conforms to standard PCB grid spacing. Round terminals facilitate easier through-hole mounting on PCBs. Gull-wing terminals on SMDs provide mechanical stability during soldering and simplified solder-joint inspection. Illuminated toggles are available.
