  • Patent number: 10242819
    Abstract: A key structure includes a supporting plate, a triggering switch, a keycap and a soft element. The triggering switch is located over the supporting plate. The keycap is located over the triggering switch. When an external force is received by the keycap, the triggering switch is pushed by the keycap. The soft element is disposed on an inner surface of the keycap. When the soft element is contacted with the triggering switch, the soft element is subjected to deformation. When the soft element is contacted with the triggering switch, a portion of the triggering switch is inserted into the deformed soft element to limit a sliding action of the triggering switch.
