Tamper Resistant IP65 Rated YB2 Series



NKK Switches and Digi-Key offer 22mm panel seal pushbutton switches

Tamper Resistant YB2 Series Switches With the YB2 Series, NKK has simplified the entire process of sampling, selecting and ordering industry standard 22mm panel seal pushbuttons to help eliminate errors and save time. The YB2 comes fully assembled making it easy to install and at 1.8mm, these pushbuttons have one of the shortest above panel dimensions in the industry. These switches exhibit a short behind-the-panel body, measuring only 24.5mm. In addition, the series has a tamper resistant 19mm actuator with a distinctive long stroke and user-friendly actuation.    YB2 Series Datasheet

Overview

Design engineers can choose either power-rated or logic-level options. Ratings are 3A at 125VAC, 3A at 250VAC or 3A at 30VDC for power models and 0.4V maximum at 28V AC/DC maximum for logic-level versions. Available in SPDT and DPDT momentary or maintained action, this series provides crisp actuation through the snap-action contact mechanism, which helps ensure clear circuit status. Terminals are combination solder lug and .110” quick connect. The epoxy seal locks out flux, dust, solvents and other contaminants as well as secures the terminals for contact stability.

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 actuator are available upon request. Bezel options are silver or black. Choice of cap colors for non-illuminated models includes white, red, green, yellow or metallic silver for enhanced panel design.
