A power saving method for a wireless input device for an electronic product, a power supply module being provided to supply power to electronic components of the wireless input device, the method comprising the steps of:

• 1) providing a switch module to the wireless input device and electrically connecting the switch module to the power supply module;
• and
• 2) actuating the switch module by a user to allow the wireless input device to enter a complete power-saving mode or an incomplete power-saving mode;
• whereby, when the wireless input device is in the complete power-saving mode, the switch module disconnects the supply of power from the power supply module to the wireless input device;
• and when the wireless input device is in the incomplete power-saving mode, the supply of power from the power supply module to the wireless input device is maintained.
