NKK Intros 24mm IP65 Panel Seal PBs
Pushbutton panel switches.
Scottsdale, AZ — NKK Switches has introduced the YB2 Series of 24mm square, flush mount and tamperproof panel seal pushbutton switches. These devices are especially suitable for applications that require 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. According to the company, the new square YB2 Series gives design engineers a robust switching device with a multitude of options. This customization allows the company to tailor each YB2 device they order to meet their precise needs.

Available in both illuminated and non-illuminated models, the new switches have an 18mm diameter square actuator. They also have the industry's shortest above-panel dimension of 1.8mm 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 use 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 the company on 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, these switches provide crisp actuation due to 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 at 125VAC, 3A at 250VAC or 3A at 30VDC for power models, and 0.4VA@28VAC/DC maximum for logic level versions. The switches have a flammability rating of UL94V0. Mechanical life is said to be 1,000,000 operations minimum for momentary circuits and 200,000 operations minimum for maintained circuits. Electrical life is 100,000 operations minimum.

Switch terminals are a combination of solder lug and 0.110-in. (2.79mm) quick connect. The epoxy seal locks out flux, dust, solvents and other contaminants, while securing the terminals for contact stability. The switches are cULus recognized when ordered with /CUL marking on the switch.
