C&K Components Expands KMT Series to Include Ultra-Low Profile, Double-Action Switch

The miniaturization trend of mobile and handheld devices continues to be driving factor in the development of innovative switches. To meet the increasing demand, C&K Components has developed a surface-mount, double-action switch that increases functionality while decreasing the footprint, said Jerome Smolinski, senior product manager for C&K Components. The ultra-miniature, double-action KMT 6 Series provides a nice tactile feel and is an ideal solution for applications requiring a small footprint and good tactile feedback on both actions. The additional IP68 rating makes it an excellent choice when protection against dust, sweat and water is needed.

The RoHS-compliant and halogen-free ultra-miniature KMT 6 switch features a footprint of only 3.8 mm x 3.1 mm with a height of 0.76mm (including the actuator). The normally-open switches are constructed with lead-free silver plating. First actuation force is set at 1.0N and the second actuation at 2.0N with a minimum difference of 0.6N between the two forces to ensure proper discrimination.

The double-action design provides extremely good and sharp tactile feedback on both actions. The KMT 6 Series device features 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.
