See below for complete assembly of switch, LEDs and LED holders.
LED SPECIFICATIONS
The electrical specifications shown are
determined at a basic temperature of 25°C.
Center LED is an integral part of the switch.
LEDs are not sold separately.
LED circuits are isolated and require an
external power source.
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.
