Full face illumination with choice of red/green or red/yellow bicolor LEDs, as well as simultaneous bicolor illumination which produces amber. Option of legends on caps or film insert. Compact design with short body 17.0mm (.669") from PCB to top of cap and 7.5mm (.295”) 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 NKK Switches • email: [email protected] • Phone (480) 991-0942 • Fax (480) 998-1435 www.nkkswitches.com L-3 Series HB2 Quiet Actuation Illuminated Pushbutton TYPICAL SWITCH ORDERING EXAMPLE HB2 1 5 S K G03 CF JB POLE 1 SPST HOUSING K Black CIRCUIT 5 ( OFF (ON) CONTACTS & TERMINALS ) = Momentary G03 SHAPE S Gold Contacts and PC Terminals, Rated 0.4VA @ 28V AC/DC LEDS Square CAP COLORS CE Red/Yellow CF Red/Green Amber can be achieved by simultaneous illumination of LEDs.

LED circuit is independent of switch operation. If the source voltage is greater than rated LED voltage, a ballast resistor must be connected in series with the LED. The circuit diagram and formula above will assist in calculating the value of the required ballast resistor.
