Pushbuttons Show Tamper Resistance
Having combined solder lug and 0.11” quick connect terminations, NKK Switches’ YB2 Series 22-mm pushbutton switches possess tamper resistance in medical equipment and industrial and commercial control panels. The UL94V0-rated devices exhibit a dust-tight and splash-proof panel seal design to protect against low-pressure water jets from all directions and meet IP65 of IEC60529 standards. The cULus-recognized switches present a 1.80-mm above panel dimension, a 24.50-mm behind-the-panel body, and a tamper-resistant 19-mm actuator. The units offer current ratings of 3 A at 125/250 VAC and 30 VDC for power models, and 0.40 VA max. at 28 V max. for logic-level versions. The SPDT and DPDT pushbuttons present momentary or maintained action, snap-action contact mechanism, min. mechanical life of 100k (momentary) or 200k (maintained) operations, and min. electrical life of 100k operations. Illuminated models offer blue, white, red, green, or amber LED options.
