Distinctive Characteristics
Wide selection of illumination effects is achieved with single and bicolor,
1- or 6-element LEDs in flat, beveled, or sculptured caps.
Alternating legends in choice of sculptured or flat caps, combined
with super bright bicolor LED.
Combination of PCB mountability and short body
allows use in compact applications.
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.
Latchdown mechanism, independent of switching
mechanism, gives outstanding stability and
reliability plus visible and tactile indication of
circuit status.
Terminals are epoxy sealed to lock out flux, solvents,
and other contaminants.
Momentary and alternate action circuits available in the same
space-saving body size.
Matching indicators available.

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