NKK Switches, the world’s leading designer and manufacturer of innovative electromechanical switches, announced the availability of the YB2 Series of 24mm square, flush mount and tamperproof panel seal pushbutton switches. These YB2 devices are ideal for applications requiring a low-profile, yet secure and splash proof design.

“Every interface design has its own special requirements, especially those that will be used in potentially damaging environments,” said Michael Wada, VP Business Development, NKK Switches. “The new square YB2 Series gives design engineers a robust switching device with a multitude of options. This customization allows them to tailor each YB2 device they order to meet their precise needs.”

Available in both illuminated and non-illuminated models, these YB2 Series switches feature an 18mm in diameter square actuator. They also boast the shortest above panel dimension of 1.8mm in the industry for a splash proof device. The tamperproof design is complemented by dust tight and splash proof panel seal protection, providing a defense against low pressure jets of water from all directions. These devices meet IP65 of IEC60529 standards.

The illuminated pushbuttons feature bright or super bright LEDs. Super bright LED options include blue, green and white. Bright LEDs are available in red, green and amber, with matching color caps and built in ballast resistors. Custom legends on the actuator are available from NKK upon request. Bezel options are silver or black. Cap color options for non-illuminated models include white, red, green, yellow or metallic silver for an enhanced panel design.

Available in SPDT and DPDT momentary and maintained action, this series features crisp actuation provided by the snap-action contact mechanism. This ensures clear circuit status and is supplemented with a latch-down actuator for maintained models. The YB2 Series also has a distinctive long stroke and light actuation.

Design engineers can also choose either 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.

The YB2 series has a flammability rating of UL94V0. Mechanical life is 1,000,000 operations minimum for momentary circuits and 200,000 operations minimum for maintained circuits. Electrical life is 100,000 operations minimum.

Terminals 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. cULus recognized when ordered with /CUL marking on the switch.
