C&K Switches KXT3 Ultra-Low Profile Tactile Switches

C&K Switches KXT3 Ultra-Low Profile Tactile Switches are top actuated tactile switches ideal for use in next-generation, ultra-compact electronics. The switches feature a laser bonded sealing film that makes the switch less sensitive to sweat or other contaminants. With a 3.0mm x 2.0mm footprint and 0.58mm thickness, C&K KXT3 Switches offer a 12VDC maximum voltage, 50mA maximum DC current, and 100VAC (1mn) dielectric strength. Typical applications include wearable electronics, in-ear headphones and earbuds, mobile phones, portable electronics, and hearing aids.
