They have mechanical life of one million operations minimum for momentary models and 200,000 operations minimum for alternate action circuits. Engineers can specify between multiple model options, making the UB series ideal for compact, design-specific applications. The pushbuttons feature snap acting contact mechanism providng sensitive actuation and audible, tactile feedback. Quick make, quick break feature limits arcing and prolongs electrical life. The illuminated modesl are supplied standard with Bright LEDs in red, green, or amber and Super Bright LEDs in green, blue, or white in all square models.
