The invention relates to the field of electrical switches, in particular to a hybrid control switch, which comprises a mechanical switch, a control device and controllable discharge gap/semiconductorswitches, and is characterized in that the controllable discharge gap/semiconductor switches are arranged at two ends of the mechanical switch in parallel; the control device is connected with the closing trigger signal, and when the control device receives the closing trigger signal, the mechanical switch and the controllable discharge gap/semiconductor switches are controlled to be closed at thesame time; and the controllable discharge gap/semiconductor switches are controlled to be switched off after the mechanical switch is switched on. When the controllable discharge gap/semiconductor switches are closed, the whole circuit is conducted, the response speed of circuit conduction is improved, and the delay caused by the action of a mechanical switch is avoided; and then the mechanical switch is successfully switched on, the controllable discharge gap/semiconductor switches are controlled to be switched off, the current stress is borne by the mechanical switch, the controllable discharge gap/semiconductor switches are prevented from bearing the current stress for a long time, and the control switch has the characteristics of short action time and high through-current capability.
