Surface-mount KXT series switches have an ultra-low board-mounted profile of just 0.58 mm. C&K has developed an ultra-low-profile, top-actuated surface-mount switch for use in applications that require ultra-miniature components, including wearable electronics, hearing aids, ear buds, mobile phones, and other portable electronics. Measuring a slight 3.0 mm x 2.0 mm x 0.58 mm, the KXT series momentary action switches are rated for a range of operating forces with an operating life of 300,000 cycles.

KXT series devices are momentary action, single pole/single throw (SPST), normally open (NO) switches with a travel distance of 0.13 mm (±0.05 mm). Available in a range of operating forces - 100 gf (±30), 180 gf (±50), and 240 gf (±70) - all of which have a 300,000 cycle operating life, the series is rated for 12 V_DC/50 mA and operating temperatures spanning -30°C to 85°C.
