when the push switch is fixed at the second position, the controller is coupled with the electromagnet assembly, and when the push switch is pressed by another external force, the trigger piece generates the control signal to the controller so as to control the electromagnet assembly to be powered off.

11. An electronic product, comprising:

a charging device as claimed in any one of claims 1 to 10; and

and the electronic device is provided with a third electrical connecting part and a magnetic attraction part which are adjacent, when the magnetic attraction component of the charging device is attracted with the electromagnet component, the magnetic attraction component is further attracted with the magnetic attraction part of the electronic device, so that the first electrical connecting part of the charging device is electrically connected to the third electrical connecting part of the electronic device.
