Abstract

An electronic switch and a control method for an electronic switch, which are applied to the technical field of electronic devices. In an electronic switch, in the time period of controlling a main switch from power-off to power-on by a control unit, the change in a current on a load is mainly caused by the change in the voltages at the two ends of the main switch in this time period, while an electricity taking circuit continues to be charged in this time period, so that the voltages at the two ends of the main switch will not become zero. Thus, in this time period, the voltages at the two ends of the main switch will not suddenly change from zero but will suddenly change from a charging voltage of the electricity taking circuit, so that the rate of change is smaller, and the change in the current on the load is also smaller, thereby reducing the electromagnetic interference due to larger rate of change in the current of the load, that is, reducing the electromagnetic interference of the electronic switch.
