Full face illumination with choice of red/green or red/yellow bicolor LEDs, as well as simultaneous bicolor illumination which produces amber. D Option of legends on caps or film insert. Compact design with short body .669 (17.0mm) from PCB to top of cap and .295 (7.5mm) square cap. Sliding Twin Crossbar (STC) mechanism provides unequalled logic-level reliability, contact stability, smooth positive detent actuation, and long life. Crimped power terminals ensure secure PCB mounting and prevent dislodging during soldering. Suitable applications include broadcast, telecommunication, and medical equipment, as well as measuring instruments, etc. Actual Size www.nkkswitches.com D19 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers Toggles
