Low Profile Pushbuttons Series UB Distinctive Characteristics 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. 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 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 at the end of Section M.

LED circuit is isolated and requires external power source. Polarity marks are on the bottom of the switch. If the source voltage exceeds the rated voltage, a ballast resistor is required. The resistor value can be calculated by using the formula in the Supplement section. The LED is an integral part of the switch and not available separately.
