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 compact KMT0 Series tactile switch meets the requirements for the EN-14604 test button, it is also IP68-rated and withstands gas corrosion tests, making it suitable 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 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.
