Claim 18:
19. 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, the upper shell having a main body, the main body being disposed to a bottom surface of the first button and a bottom surface of the second button, the bottom surface of the first button extending downward to form a first pressing portion, the bottom surface of the second button extending downward to form a second pressing portion and a third pressing portion, an inside of the first pressing portion forming a first space penetrating through a rear of the first pressing portion, an inside of the second pressing portion forming a second space penetrating through a rear of the second pressing portion, and an inside of the third pressing portion forming a third space penetrating through a rear of the 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;
a first elastic element disposed to a bottom surface of the upper shell, the first elastic element being corresponding to the first button, the first elastic element having a first elastic body, the first elastic body being mounted under one side of the main body which is disposed to the bottom surface of the first button, a bottom end of the first elastic body having a first abutting end, one end of the first abutting end abutting against an inner surface of a lower wall of the first space 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, the second elastic element having a second elastic body, the second elastic body being mounted under the other side of the main body which is disposed to the bottom surface of the second button, a top end of the second elastic body having a second abutting end, a free portion of a bottom end of the second elastic body extending downward, then extending frontward and further slantwise extending frontward and upward to form a flexible arm, a tail portion of the second abutting end abutting against an inner surface of a lower wall of the second space of the second pressing portion to generate a second downward force, one end of the flexible arm abutting against an inner surface of a top wall of the third space 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.
