Product
Part Number
Appearance
The B Illuminated Toggles will have a change to the LED specifications for Red, Amber, Green,
and bicolor Red/Green. The change will effect all illuminated models, both standard and custom.
The specification changes are outlined below, followed by effected standard part numbers.
LED Changes for
B Illuminated Toggles
LED COLORS & SPECIFICATIONS
LEDs are supplied as an integral part of illuminated devices and are not available separately.
The electrical specifications shown here are determined at a basic temperature of 25°C.

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
E
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.
