Tactile Switches
Tactile Switches are switches or switch assemblies that provide a positive snap-action response. This response can be achieved through the use of stainless steel domes embedded in the membrane switch or by polyester domes formed in either the circuit layer or the graphic overlay.
Tactile switches can either be coupled or decoupled. Coupled switches use a conductive tactile device to complete the circuit. Decoupled switches, on the contrary, utilize the mechanical properties of the tactile device to complete the circuit, so the device does not need to be conductive.
Tactile switches come in a wide variety of sizes, shapes, and actuation forces. Using different sizes of metal domes or polydomes will vary the actuation force. Metal domes come in a large assortment of shapes and sizes with actuation forces between 180 to 700 grams; different polydome actuation forces can be achieved by changing the diameter and height of the polydome to meet specific requirements.
