A series of tamper-resistant, 22-mm panel-seal switches are aimed at applications in public locations or where there is a need for greater protection from environmental conditions, such as medical equipment and industrial control panels.The YB2 series of pushbuttons are offered in both illuminated and non-illuminated models, are flush mountable, and have a low profile. The dust-tight and splash-proof panel seal design protects the YB2 series against low pressure jets of water from all directions and meets IP65 of the IEC60529 standards. The above-panel dimension is 1.8 mm while the behind-the-panel body measures 24.5 mm. In addition, the series has a tamper resistant 19-mm actuator with a distinctive long stroke and user-friendly actuation. Designers can choose either power-rated or logic-level options. Ratings are 3 A @ 125 VAC, 3 A @ 250 VAC, or 3 A @ 30 VDC for power models; and 0.4 VA maximum @ 28V AC/DC maximum for logic-level versions. The switches are available in SPDT and DPDT momentary or maintained action, and provide crisp actuation through the snap-action contact mechanism. Terminals are combination solder lug and 0.110-in. quick connect. Mechanical life is one million operations minimum for momentary circuits, and 200,000 operations minimum for maintained circuits. Electrical life is 100,000 operations minimum. NKK SWITCHES, Scottsdale, AZ. (480) 991-0942.
