C&K claims industry's most compact EN-14604-certified switch



C&K Components, a leading international supplier of tact switches, toggle and rocker switches, and smart card interconnect devices, has expanded its line of switch products for smoke detectors in support of the new European EN-14604 standard. According to the new regulation, all smoke detectors sold in the European Union must include the CE marking and comply with EN-14604 standards, which require all smoke detectors to be equipped with a test button. The KMT0 Series tactile switch from C&K is the most compact switch on the market that meets the requirements for the EN-14604 test button. Moreover, the IP68-rated switch's ability to withstand gas corrosion tests makes it the ideal solution for harsh environment applications typical with many smoke detector installations. The KMT0 Series features a low-profile of 0.65mm with integrated actuator and an operating life of up to one million cycles. An ultra-low current version is also available, which extends battery lifetime. In addition, C&K's KSA/KSC Series sealed tactile switches feature customizable actuation and button height. The top- or side-actuated KSA/KSC Series switches are surface mountable and deliver a specific actuator with a groove for button clipping and compatibility. The IP67-sealed KSA/KSC Series switches have a unique design that provides simple integration with an operating life up to one million cycles. The combination of IP67 sealing and gold plating offer a high resistance level against ingressions and corrosion agents which leads to reliability and service life required by fire detection applications. Another switch product that meets the requirements for smoke/fire detectors and carbon monoxide detectors is the KSE Series of cost-effective, low-profile tactile switches. These momentary-action tactile switches combine rugged IP67-rated sealing, reliability and a long operating life with an optimized, economical design. Ideal for identifying the location of smoke detectors on the premises, the miniature RTE Series of low-profile rotary DIP switches are available in surface mount and through-hole models. The RTE Series DIP switches feature SPDT, SP3T and SP4T rotary functions, as well as rotary binary-decimal and hexa-decimal coding. With a robust stainless steel cover, the RTE Series has an operating life of up to 20,000 actuations. C&K Components
