1. A mouse, comprising:
a lower shell;
an upper shell covered on the lower shell, a middle of the upper shell being spaced from the lower shell to form an accommodating space between the lower shell and the upper shell, a front end of the upper shell having a first button and a second button, a bottom surface of the first button extending downward to form a first pressing portion, a bottom surface of the second button extending downward to form a second pressing portion and a third pressing portion, the front end of the upper shell being closer to the first pressing portion of the first button than to the second pressing portion and the third pressing portion of the second button;
a first elastic element disposed to a bottom surface of the upper shell, the first elastic element being corresponding to the first button, one end of the first elastic element abutting against a lower wall of an inside of the first pressing portion to generate a first downward force;
a second elastic element disposed to the bottom surface of the upper shell, the second elastic element being corresponding to the second button, one end of the second elastic element abutting against a lower wall of an inside of the second pressing portion to form a second downward force, the other end of the second elastic element abutting against a top wall of an inside of the third pressing portion to generate a resilience force; and
a circuit board fastened in the accommodating space, the circuit board being equipped with two electronic switches, the two electronic switches being mounted on two opposite sides of a front end of a top surface of the circuit board, the two electronic switches being corresponding to the first pressing portion and the third pressing portion;
wherein the first downward force is equal to a sum of the second downward force and the resilience force.
