LED is an integral part of the switch and not available separately.
The LED circuit is independent of switch operation.
Electrical specifications are determined at a basic temperature of 25°C.
If the source voltage exceeds rated voltage, a ballast resistor is required.
The resistor value can be calculated by using the formula shown here.

There is no change to the specifications of the white LED.
There is no change to the dimensions of the switches.
Due to the change of Forward Voltage (VF ), the external resistor value may be affected. Contact the factory if further details are needed.
Availability
TL Series with new LED specifications will be available with June 2009 production.
