Scottsdale, Ariz. − NKK Switches has expanded its YB2 Series of 24-mm square and 25-mm round tamperproof pushbuttons with a brushed chrome cap and bezel option for non-illuminated models. The brushed chrome alternative to silver provides the look of a stainless steel switch without the added weight due to "high quality metal plating on top of a sturdy resin foundation," said NKK.
The series also provides clear, red, green or amber cap options for non-illuminated models and a black bezel. Illuminated models feature bright or superbright LEDs available in blue, white, red, green or amber, with matching color caps and built in ballast resistors. Custom legends on the caps are available for both non-illuminated and illuminated models.
When selecting the brushed chrome cap option, outer ring illumination is also available in all the bright and superbright LED colors. The outer ring illumination is diffused through a clear outer ring, framing the center in a halo of light.
Available in SPDT and DPDT momentary and maintained action, all YB2 Series devices feature crisp actuation provided by the snap-action contact mechanism. Maintained models also feature a latch-down actuator.
The YB2 switches use terminals that are a combination of solder lug and .110" quick connect. The epoxy seal locks out flux, dust, solvents and other contaminants, as well as securing the terminals for contact stability. These devices are cULus recognized when ordered with a "/CUL" marking on the switch. The switches are IP65 rated.
The switches are available with power rated or logic level options. Ratings are 3A@125V AC, 3A@250V AC or 3A@30V DC for power models, and 0.4VA@28V AC/DC maximum for logic level versions. Mechanical life is rated at 1,000,000 operations minimum for momentary circuits and 200,000 operations minimum for maintained circuits. Electrical life is rated at 100,000 operations minimum.
