C and K Expands Range of Smoke Detector Switches
Test switches for smoke detectors.
Newton, MA — C and K Components 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 is said to be 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 an excellent solution for harsh environment applications typical of many smoke detector installations. The KMT0 Series has 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, the company's KSA/KSC Series sealed tactile switches provide 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 switches have a special 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 corrosive agents which leads to the reliability and service life required for 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. Excellent for identifying the location of smoke detectors on the premises, the miniature RTE low-profile rotary DIP switches are available in surface mount and through-hole models. The RTE Series DIP switches provide 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.
