Abstract
A noise reduction key structure is disclosed. The noise reduction key structure is applied to an electronic device having a housing and a substrate, the substrate being installed in the housing, the housing having a key portion, the noise reduction key structure comprising: a switch element which is installed on the substrate in response to the key portion; and an encapsulation which has a hole, wherein the hole encapsulates on the up side of the substrate, so that the substrate and the encapsulation together encapsulate the switch element into a chamber of the encapsulation, whereby when the key portion is pressed down, the key portion triggers the encapsulation to further trigger the switch element, and the encapsulation can reduce the noise of triggering the switch element.
