Distinctive Characteristics
Pushbuttons
Red/green and amber/blue bicolors with alternating standard or custom legends.
Super bright LED provides brilliant uniform illumination.
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
Combination of PCB mountability and short body
allows use in compact applications.
Keylocks
Small behind panel dimension for snap-in
mounting in tight spaces.
Programmable Illuminated PB
Low Profile Pushbuttons
Slides
Rotaries
Snap-acting contact mechanism provides
sensitive actuation with audible feedback;
quick-make, quick-break characteristic
limits arcing and prolongs electrical life.
Tactiles
Latchdown mechanism, independent of switching
mechanism, gives visible and tactile indication of
circuit status.
Tilt
Terminals are epoxy sealed to lock out flux, solvents, and
other contaminants.
Matching indicators available.
Touch
Momentary and alternate action circuits available in the same
space-saving body size.

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.
