BUTTON ASSEMBLY AND ELECTRONIC DEVICE HAVING THE SAME

摘要

An exemplary button assembly for use in an electronic device includes a casing, a switch, a button, a spacer, and a coil spring. The casing is connected to the electronic device. The switch is arranged under the casing. The button is received in the casing. The spacer is received in the casing and arranged between the button and the coil spring. The spacer is attached to the button and configured to actuate the switch when the button is pressed. The coil spring is received in the casing and arranged between the button and the casing. A diameter of the coil spring approximately equals that of the flange of the button, thereby providing an elastic force towards a keystroke axis of the button when the button is released, and the elastic force improves stability of the button while the button is returning to its original position.

主权项

1. A button assembly for use in an electronic device, the button assembly comprising:
a casing connected to a top plate of the electronic device; a switch arranged under the casing; a button movably received in the casing, the button comprising a flange; a spacer movably received in the casing and arranged between the button and the coil spring, the spacer being attached to the button and configured to actuate the switch when the button is pressed; and a coil spring movably received in the casing, and arranged between the button and the casing; wherein a diameter of the coil spring approximately equals a diameter of the flange, thereby allowing the coil spring to provide a first elastic force substantially parallel to a keystroke axis of the button when the button is released and urge the button to return to its original position.
