Distinctive
Characteristics
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.
Combination of PCB mountability and short body
allows use in compact applications.
D
Snap-acting contact mechanism provides
sensitive actuation with audible feedback;
quick-make, quick-break characteristic
limits arcing and prolongs electrical life.
Terminals are epoxy sealed to lock out flux, solvents, and
other contaminants.
