C&K has a wide portfolio of miniature and ultra-miniature Tact switches for use as menu navigation and function buttons on Smart Glass devices.  The product focus is on miniature form factor, resistance to corrosion, adjustable haptics, and long cycle life.  Current products have footprints as small as 3mm x 2mm with a minimum height of 0.6mm and are well suited to the minimum footprint requirements of modern wearables devices.  For designers who want to perform two functions with the same tact switch, C&K also has a double action tact switch available with two different actuation forces.
