Characteristics
Bright or super bright LEDs (an integral part of the switch) of red,
amber, green, blue, or white, in full face or spot illumination
plus square or rectangular models.
D
Small behind panel dimension for snap-in
mounting in tight spaces.
Snap-acting contact mechanism provides
sensitive actuation with audible feedback;
quick-make, quick-break characteristic
limits arcing and prolongs electrical life.
Momentary and alternate action circuits available in the
same space-saving body size.

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.
