NKK Switches Announces UB Series Illuminated and Non Illuminated Pushbuttons
Scottsdale, Ariz. (November 24, 2003) - Extending it's dedication to provide innovative switch design, NKK Switches' extensive offering of pushbutton switches now includes the low profile, illuminated and non-illuminated UB series. NKK Switches' UB series offers a myriad of choices to meet the needs of even the most demanding of applications. The UB series provides power or logic level rated devices in an extremely compact body, boasting a behind-panel depth of merely .394" (10mm). Square models have a panel cutout of .628" (16.2mm), and the rectangular devices have a cutout of .638"(16.2mm) by .882"(22.4mm).
Rated 5A @ 125/250V AC or 5A @ 30V DC for power rated models, and 0.4VA maximum @ 28V AC/DC maximum for logic level devices, these switches have a mechanical life of one million operations minimum for momentary models and 200,000 operations minimum for alternate action circuits. They are available in both single pole and double pole, double throw configurations. Alternate action circuits have a latch-down mechanism, making the circuit status instantly visible. Engineers can specify between square or rectangular, snap-in solder-lug mount and PCB mount models. The rectangular models can be ordered with built-in side barriers, and both shapes feature a built-in bezel. Any combination allows for their use in compact applications.
These devices feature a snap-acting contact mechanism providing sensitive actuation and audible, tactile feedback. In addition, they are quick make, quick break which limits arcing and prolongs electrical life.
Illuminated models are supplied standard with Bright LEDs in red, green or amber. As a further enhancement to this series, design engineers can specify Super Bright LEDs in green, blue or white in all square UB series switches. LEDs are an integral part of the switch, with an isolated circuit for versatility. Cap styles include full-face illumination through a variety of colored lens and diffusers or black spot illuminated. Non-illuminated UB switches can be ordered with brightly colored caps, as well as clear or white.
Engineers can choose from a full array of matching and complimentary indicators. In addition, the UB series has a variety of accessories available, including splash-covers and spring loaded protective covers for snap-in models. The UB family of devices lends itself easily to legending. Legend packets, which are designed to facilitate design engineers' specifications are available on line or can be requested from the factory.
The UB series is UL Recognized and CSA Certified. The flammability rating for the housing/bezel and base is UL94V-0. A leading designer and producer of electromechanical switches, NKK Switches offers one of the industry's most extensive selections of illuminated, process sealed, miniature, specialty and surface mount switches. The company manufactures more than three million toggle, rocker, pushbutton, slide, rotary, DIP rotary, keypad and keylock switches. NKK Switches maintains a complete network of qualified representatives and distributors through the United States, Canada, Central and South America, Europe and Asia.
