Abstract:
1. A switching device switchable between an electrically isolating off-state and an electrically conductive on-state, comprising: a reactive metal electrode; an inert electrode; and a solid state electrolyte arranged between the electrodes and being capable of electrically isolating the electrodes to define the off-state, wherein the reactive metal electrode and the solid state electrolyte forming a redox-system having a turn-on voltage to start a redox-reaction, the redox reaction resulting in generating metal ions to be released into the solid state electrolyte, the metal ions being reduced to increase a metal concentration within the solid state electrolyte, wherein an increase of the metal concentration results in a conductive metallic connection bridging the electrodes to define the on-state.
