| Low Profile Pushbuttons Series UB2 Distinctive Characteristics 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. Latchdown mechanism, independent of switching mechanism, gives visible, audible, 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. Illuminated models available and shown in Illuminated Pushbutton section. Matching indicators available and shown at the end of Section M.
