Notes
• The LED circuit is isolated and requires 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
shown here.
• The changes to LED specifications do not effect any external
dimensions of the switches.
• Contact the factory if further details are needed.
