An electronic device includes a switch, a housing, a button, and an elastic element. The housing includes a cover and a sidewall enclosing the cover. The sidewall defines a receiving hole. The button is received in the receiving hole. The elastic element includes a base, a resisting portion, and an angled elastic arm connecting the resisting portion to the base. The resisting portion abuts against the button. The base is fixed to the cover. The elastic arm deflects when the button is pushed by an external force to actuate the switch, and rebounds to cause the button to move back when the external force has ceased. |
