Alternating legends in choice of sculptured or flat caps, combined with super bright bicolor LED. Combination of PCB mountability and short body D 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.
