Switching devices are provided. The switching devices include an input electrode, having a main electrode and a trigger electrode, and an output electrode. The main electrode and the trigger electrode are separated from the output electrode by a main gap and a trigger gap, respectively. During operation, the trigger electrode compresses and amplifies a trigger voltage signal causing the trigger electrode to emit a pulse of energy. This pulse of energy form plasma near the trigger electrode, either by arcing across the trigger gap, or by arcing from the trigger electrode to the main electrode. This plasma decreases the breakdown voltage of the main gap. Simultaneously, or near simultaneously, a main voltage signal propagates through the main electrode. The main voltage signal emits a main pulse of energy that arcs across the main gap while the plasma formed by the trigger pulse is still present.
