Embossing Metal Dome Membrane Switch, Metal Dome Membrane Keypad FPC Circuit

Integrating metal domes into your application is simple—if you know the components necessary to complete the switch assembly. Whether you are assembling a membrane switch, keypad, or other types of switch, metal domes are critical components. Other parts of the switch may include graphic overlays, adhesives, circuits, and spacers.
Product designers can control a lot of the user interface requirements at the dome level. Requirements may include force, travel, audibility, or tactile feedback for your product. Other dome features designers should take into consideration are backlighting, built-in actuators, over-travel, and more.
