UB2

Low Profile Pushbuttons
Series UB2
Distinctive Characteristics
Wide selection of illumination effects is achieved with single and bicolor,
1- or 6-element LEDs, in flat, beveled, or sculptured caps. LED colors
include red, amber, green, white, blue, and orange (achieved by
lighting red and green simultaneously).
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.
Patented 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.
Nonilluminated models available and shown in Pushbutton
section.
Matching indicators available and shown in Indicator section.

LED COLORS & SPECIFICATIONS
Electrical specifications are determined at a basic temperature of 25°C. LED circuit is independent of switch operation.
If the source voltage is greater than rated voltage, a ballast resistor is required.
The ballast resistor calculation and more lamp detail are shown in the Supplement; see Supplement Index (page Z1).
