Featuring a 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.
“The KMT0 Series underwent extensive and rigorous testing, including a 5 hour submersion in 2 meters of water, to meet IP68 sealing requirements,”
The RoHS-compliant and halogen-free ultra-miniature KMT0 switches feature a footprint of only 3.0mm 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: 1.0N, 1.6N, 2.3N and 3.4N. Maximum overload is 30N.
Actuator height is only 0.2mm, and the integrated actuator allows for simpler button design while yielding an excellent tactile ratio minimum 30%, providing sharp feedback (low tactile ratio of 10% 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 – 32Vdc with a minimum/maximum current rating of 1mA – 50mA. The operating temperature ranges from -40°C to +85°C.
