Ultra-Miniature IP68-Rated Tactile Switch

C&K Components' KMT0 Series of ultra-miniaturetactile switches to provide IP68-rated sealing. The KMT0 Series is completelysealed and stays fully functional under water for a minimum of 5 hours at adepth of 2 m. The KMT0 Series is fully resistant to the most stringentconformal polymer coatings, including one of the smallest particle chemicalvapors, parylene, which is used for coating printed circuit boards (PCBs) andmedical devices.

TheRoHS-compliant and halogen-free ultra-miniature KMT0 switches feature a footprintof 3.0 x 2.6mm with a height of 0.63 or 0.65mm. The SPST (single pole singlethrow) normally-open switches are constructed with silver plating and areavailable with four operating forces: 1.0, 1.6, 2.3 and 3.4N. Maximum overloadis 30N. Actuator height is 0.2 mm, and the integrated actuator allows forsimpler button design while yielding an excellent tactile ratio minimum 30percent, providing sharp feedback (low tactile ratio of 10 percent is availablefor hearing aids and headsets). The KMT0 Series devices feature a maximum powerrating of 0.5VA and a minimum/maximum voltage of 20mV - 32V dc with aminimum/maximum current rating of 1mA - 50mA. The operating temperature rangesfrom -40 to +85C.

Featuring alifespan of more than 300,000 electrical and mechanical cycles, the KMT0 Seriestactile switch's ultra-low profile makes it a viable solution for handheld andportable electronic device applications that require a small footprint, whilethe IP sealing is an excellent solution to protecting against perspiration andwater in portable devices.
