NKK Switches announced the availability of the YB2 Series of 24-mm square, flush mount and tamperproof panel seal pushbutton switches. These devices are appropriate for applications requiring a low-profile, yet secure and splash proof design. Available in both illuminated and non-illuminated models, these switches feature an 18-mm in diameter square actuator. They also boast the shortest above panel dimension of 1.8 mm in the industry, according to the company, 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. Available in SPDT and DPDT momentary and maintained action, this series features crisp actuation provided by the snap-action contact mechanism.
Design engineers can also choose either power rated or logic level options. Ratings are 3 A at 125 V AC, 3 A at 250 V AC or 3 A at 30 V DC for power models, and 0.4 VA at 28 V 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.
