Ultra-Miniature Tactile Switch

The KMT Series of ultra-miniature tactile switches now offers the new KMT0 ultra-miniature tactile switch, which features a life span of more than 300,000 electrical and mechanical cycles, and is sealed to IP57 specifications. The ultra-miniature size provides an ideal solution for applications with an extremely small footprint, while the IP sealing is an excellent solution to protecting against sweat and water in nomad devices. The RoHS-compliant and halogen free ultra-miniature KMT0 switches measure just 2.6 x 3.0 x. 0.65mm, with a body height of 0.45mm. The SPST NO 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 0.2mm, and the integrated actuator allows for simpler button design while yielding an excellent tactile ratio of up to 30%, providing sharp feedback (low tactile ratio of 10% is available for hearing aids and headsets). Operating temperature ranges from -40°C to +85°C.
