Arrow is now offering NKK Nikkai’s UB2 series of low-profile, illuminated pushbutton switches, with enhanced features and expanded aesthetic and functional options. These provide engineers with an exceptional choice to replace standard, outdated, split-legend caps.
The UB2 super-bright, red/green, bi-color LED switch selections can be specified with alternating standard legend configurations. Standard, off-the-shelf legends include ON/OFF, START/STOP, or OPEN/CLOSE.

The glossy polycarbonate cap features a single filter with a dual legend, under the clear lens. When actuated, the green or red LED brilliantly highlights the alternating legends, clearly indicating the desired circuit status. Legends are in black text and the cap styles for these devices include sculptured or flat. Companion or stand-alone indicators are also available with the dual-legend options.

The UB2 series is a unique, miniature, low profile lighted switch family designed for use in applications requiring a compact and brilliantly illuminated switch solution. Its features include built-in, multi-element LEDs. Single-pole/double-throw and dual-pole/double-throw in momentary and maintained circuit configurations can be specified. Maintained circuit models feature a latch-down mechanism to indicate circuit status.

UB2 switches are available in snap-in mount or PCB mount versions. The snap-in mount version is solder lug, with a behind-panel depth of 15mm, while the PCB mount version has a behind-panel depth of 10mm. Terminals are epoxy sealed to lock out flux, solvents and other contaminants.

The UB2 pushbuttons are also available in power rated and logic level rated models. These highly reliable devices are rated 5A @ 125/250V AC or 5A @ 30V DC for power rated models, and 0.4VA maximum @ 28V AC/DC for the logic level models. Mechanical life is rated at 1,000,000 operations minimum for momentary circuits and 200,000 operations minimum for maintained action. The housing is constructed of glass fibre reinforced polyamide. Both the housing and base meet UL94V-0 flammability standards. The UB2 series is UL and C-UL recognised.
