Rich Text Editor, richEditorWhat is Metal Dome Arrays and How does it work ?
Metal domes is made of stainless steel , is a switch accessory , also known as : tactile metal domes , metal snap domes , tactile domes , dome switches , click domes , snap domes and etc , in comparison with traditional silicone button, more sensitivity conductivity , Longer life-time .
The metal dome keypad located around PCB conductive area ( most is located above PCB gold finger ) , when pressed , center of dome will sink to touch with PCB circuit , to form a loop circuit . The current passes through and the whole product works normally
