A gas discharge switch that has at least two coaxial electrodes which are provided with coaxial holes and form in a central discharge region, a gas discharge path, and an insulating region at their edges. The spacing D in an axial direction of the electrodes is larger than the spacing d1 of the electrodes at the inner edge of a washer-like insulator in the insulating region. The electrodes are respectively connected to one of the flat sides of the insulator, and the spacing d1 is at least as large as the spacing d2 of the electrodes in a shielding region that is formed between the insulating region and the discharge region. A shield that shields the insulator from the discharge region is provided.
