Lightweight Metal Dome Membrane Switch With PET/PC/PMMA/PVC Flat
Push Buttons
What is Metal Dome Membrane Switch ?
Metal Dome Membrane Switch is a momentary switching device that is manufactured by using a
series of flexible layers of polymer films and adhesives. The top
layer, called a graphic overlay, is manufactured by printing on the
down surface of transparent polyester or polycarbonate film.
Membrane switches can be constructed of multiple circuit layers,
and more optimized graphic design features, such as domed key
embossing. Designs that are more complex require more material
layers for proper construction and reliable operation. Membrane
switches, when combined with components such as a tactile dome,
graphic overlay, or integrated LEDs or resistors can provide the
designer with virtually limitless capabilities to create the ideal
custom user interface for their products.
