C&K Components' KMT0 Series of ultra-miniature
tactile switches to provide IP68-rated sealing. The KMT0 Series is completely
sealed and stays fully functional under water for a minimum of 5 hours at a
depth of 2 m. The KMT0 Series is fully resistant to the most stringent
conformal polymer coatings, including one of the smallest particle chemical
vapors, parylene, which is used for coating printed circuit boards (PCBs) and
RoHS-compliant and halogen-free ultra-miniature KMT0 switches feature a footprint
of 3.0 x 2.6mm with a height of 0.63 or 0.65mm. The SPST (single pole single
throw) normally-open switches are constructed with silver plating and are
available with four operating forces: 1.0, 1.6, 2.3 and 3.4N. Maximum overload
is 30N. Actuator height is 0.2 mm, and the integrated actuator allows for
simpler button design while yielding an excellent tactile ratio minimum 30
percent, providing sharp feedback (low tactile ratio of 10 percent is available
for hearing aids and headsets). The KMT0 Series devices feature a maximum power
rating of 0.5VA and a minimum/maximum voltage of 20mV - 32V dc with a
minimum/maximum current rating of 1mA - 50mA. The operating temperature ranges
from -40 to +85C.
lifespan of more than 300,000 electrical and mechanical cycles, the KMT0 Series
tactile switch's ultra-low profile makes it a viable solution for handheld and
portable electronic device applications that require a small footprint, while
the IP sealing is an excellent solution to protecting against perspiration and
water in portable devices.
