LED COLORS & SPECIFICATIONS

Bezel Orientation on Switch

AT070 LED

For Bezel AT208

with 1 LED

The electrical specifications shown are determined at a basic temperature of 25°C.

LED circuit is independent of switch operation. LED is colored in OFF state.

If the source voltage is greater than the rated voltage of the LED, a ballast resistor must be connected in series with the lamp.

The ballast resistor calculation and more lamp detail are shown in the Supplement section.
