6 / 14 page Series KB Miniature Pushbuttons D27 D www.nkkswitches.com CONTACT MATERIALS, RATINGS & TERMINALS Silver Contacts Gold Contacts Complete explanation of operating range in Supplement section. W G LAMP COLORS & SPECIFICATIONS The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and requires external power source. Polarity marks are on the bottom of the switch. If the source voltage exceeds the rated voltage, a ballast resistor is required. The resistor value can be calculated by using the formula in the Supplement section. Ambient Temperature Range for lamps below: –25°C ~ +50°C. Power Level 1A @ 125V AC & 250V AC Logic Level 0.4VA maximum @ 28V AC/DC 01 Solder Lug (5.0) .197 (1.8) .071 (1.0) .039 (2.0) .079 Thk = (0.2) .008 Com = (0.1) .005 A partitioned plastic guard is supplied with each switch to provide insulation between terminals. Installation steps: 1. Identify wire-to-terminal connections. 3. Solder the connections. 2. Thread wires through the guard. 4. Push the guard fully onto the switch body.
