C&K Components expanded its KMT Series of ultra-miniature tactile switches to include a double-action, double-tactile version. Featuring a low profile, the double-momentary action KMT 6 Series provides a lifespan of more than 150,000 electrical/mechanical cycles and is sealed to IP68 certifications, making it suitable for handheld and portable electronic devices. The RoHS-compliant and halogen-free ultra-miniature KMT 6 switch features a footprint of 3.8 mm x 3.1 mm with a height of 0.76 mm (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 good and sharp tactile feedback on both actions. The device features a maximum power rating of 0.5 VA and a minimum/maximum voltage of 20 mV to 32 VDC with a minimum/maximum current rating of 1 mA to 50 mA.
