Abstract
A key structure of an electronic device includes a connecting portion and a key portion. The connecting portion includes two electrode plates cooperatively defining an accommodating space. The key portion, when pressed, is moved toward the accommodating space and partially received within the accommodating space, thereby changing a capacitance between the two electrode plates. The key portion partially protrudes from the housing.
