Round Rocker Switches Resist Water’s Ingress October 10, 2008
In the KC and KD Series of round, water-resistant rocker switches, designers will find devices with a silicone rubber actuator and snap-fit mounting that result in compliance with IP56 standards. As a result, the switches are suitable for applications requiring resistance to dust and water intrusion, such as outdoor power equipment, commercial appliances, and medical equipment. Both the single-pole KC Series and the double-pole KD Series use heavy-duty silver alloy contacts to achieve current ratings of 20 A at 14 V dc and 16 A at 125 V ac. The switches fit an industry-standard panel cut-out of 20.2 mm in diameter and are available in lighted and non-lighted designs. The standard termination is 0.187-in. (4.8-mm) quick-connect tabs. The KC Series also offers 0.173-in. (4.4-mm) diameter solder tabs and PC through-hole straight termination options. The Cherry KD Series water-resistant rocker switch is UL-approved on AC loads while the KC Series is UL- and VDE-approved on AC loads. Both series are available from stock; contact the company for pricing information. CHERRY CORP., Pleasant Prairie, WI. (800) 927-6298.
