Abstract
The invention relates to a power switch which is used to control the on-off of an electronic device and a direct current power. The power switch comprises a switch key, a charging circuit, a control circuit, a trigger and a switch tube. After the charging circuit is connected with the control circuit in parallel, the charging circuit is electrically connected with the direct current power through the switch key. The trigger is connected between the control circuit and the switch tube. The switch tube comprises a first pole electrically connected with the direct current power, a second pole electrically connected with the electronic device, and a control pole electrically connected with the trigger. The control pole controls the on-off of the first pole and the second pole. When the switch key is turned on, the charging circuit is charged. When the switch key is cut off, the voltage of the charging circuit after charging drives the control circuit to work. If the voltage that the control circuit inputs to the trigger is greater than the trigger voltage of the trigger, the signal output by the trigger reverses, and the on-off state of the switch tube changes; if the voltage that the control circuit inputs to the trigger is less than the trigger voltage of the trigger, the signal output by the trigger dose not change, and the on-off state of the switch tube does not change to avoid the false operation of a user.
