Low Profile Pushbuttons
Series UB2
Toggles
Alternating legends (patent pending) 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.
