LED COLORS & SPECIFICATIONS
LEDs are supplied as an integral part of
illuminated devices and are not available
separately.
LED polarity markings are on the bottom
of the switch.
The electrical specifications shown here are
determined at a basic temperature of 25°C.
If the source voltage exceeds the rated volt-
age, a ballast resistor is required.
The resistor value can be calculated by using
the formula in the Supplement section.
