LED COLORS & SPECIFICATIONS
Rockers
The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and requires external power
source. Polarity marks are on bottom of switch. If the source voltage exceeds the rated voltage, a ballast resistor is required. Resistor
value can be calculated by using the formula in the Supplement section. LED is an integral part of switch and not available separately.
