Panel Seal Pushbuttons Series YB2 Panel Seal Pushbuttons Series YB2 BRIGHT & SUPER BRIGHT LEDS cd CD .0 The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and requires an external power source. If the source voltage exceeds the rated voltage, a ballast resistor is required. Base of AT634 and AT636 is Black for 5V, Light Blue for 12V and Gray for 24V. ■» Electrical Specifications for Bright LED without Resistor

BALLAST RESISTOR CALCULATION FOR LEDS R If the source voltage is greater than the rated voltage of a lamp or LED, a ballast resistor must be connected in series with the lamp. This circuit diagram and formula will assist in calculating the value of the required ballast resistor.
