NKK UB2

Low Profile Pushbuttons UB2 Series

Low Profile LED Pushbuttons - UB2 Series
NKK Switches offers the UB2 Series Low Profile LED Pushbuttons in a wide selection of illuminated effects with single- and bi-color, 1- or 6-element LEDs in flat, beveled, or sculptured caps. The Low Profile LED Pushbuttons in the UB2 series from NKK Switches offers alternating legends with START/STOP, OPEN/CLOSE, ON/OFF in green/red LEDs, respectively. These LED Pushbuttons with alternating legends are ideal for indoor applications in which a positive circuit status indication is critical, such as audio/visual control consoles, music recording panels, patient monitors, and diagnostic equipment.

Distinctive Characteristics

- Wide selection of illumination effects is achieved with single and bicolor, 1- or 6-element LEDs in flat, beveled, or sculptured caps.
- 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.
- Latch down mechanism, independent of switching mechanisms, 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.
- Non-illuminated modes available
- Matching indicators available
