Abstract
A key structure includes a circuit board, a housing, a first metallic element, a second metallic element, a keycap and a conductive strip. The conductive strip is disposed within the housing. The first metallic element and the second metallic element are electrically connected with the circuit board. The housing is disposed on the circuit board. The keycap is fixed on the housing. While the keycap is depressed, a first end of the conductive strip is pressed by the triggering part and the conductive strip is swung relative to the housing. Moreover, a second end of the conductive strip collides with the second metallic element. Consequently, the key structure is triggered. When the second end of the conductive strip collides with the second metallic element, a click sound is generated.
