Computer mouse capable of switching between a left-handed mode and a right-handed mode

A computer mouse capable of switching between a left-handed mode and a right-handed mode, the computer mouse comprising:

• a left button, when being pressed, producing left button signals;
• a right button, when being pressed, producing right button signals;
• an integrated circuit chip comprising:
• a left-button input pin and a right-button input pin, which is configured for receiving and processing button signals from the left button and the right button respectively;
• a control switch operable to switch between a first state and a second state;
• a first transistor-circuit;
• and
• a second transistor-circuit;
• wherein, the first transistor-circuit and the second transistor-circuit comprise a plurality of transistors;
• wherein, when the control switch is in the first state, the first transistor-circuit is enabled and transmits left button signals to the left-button input pin of the integrated circuit chip and transmits the right button signals to the right-button input pin of the integrated circuit chip;
• and
• when the control switch is in the second state, the second transistor-circuit is enabled and transmits the left button signals to the right-button input pin and transmits the right button signals to the left-button input pin of the integrated circuit chip respectively.
