Abstract: A mouse includes a lower shell, an upper shell covered on the lower shell, a first elastic element, a second elastic element and a circuit board. The upper shell has a first button and a second button. A bottom surface of the first button extends downward to form a first pressing portion. A bottom surface of the second button extends downward to form a second pressing portion and a third pressing portion. One end of the first elastic element abuts against the first pressing portion to generate a first downward force. One end of the second elastic element abuts against the second pressing portion to form a second downward force. The other end of the second elastic element abuts against the third pressing portion to generate a resilience force. The first downward force is equal to a sum of the second downward force and the resilience force.
