A method of controlling an electric desk which includes a device for controlling movement of the desk, the device including a key, a chip module, a controller, and a sensing element; when the key is depressed, the control method includes: S10: detecting, by a chip module, the trigger signals emitted from the sensing element, wherein if two trigger signals are detected, the control method proceeds to step S20, and otherwise proceeds to step S30; S20: transmitting, by a controller, the control instruction; S30: not transmitting, by a controller, the control instruction; when the key is released, the control method includes: T10: detecting, by the chip module, the trigger signals emitted from the sensing element, wherein if two trigger signals are detected, the control method proceeds to step T20, and otherwise proceeds to step T30; T20: maintaining, by the controller, the control instruction; T30: suspending, by the controller, the control instruction.
