ELECTRODE/SPARK IGNITOR

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).

An ignitor is a device used to initiate combustion - the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of a chemical state. The release of heat can also result in the production of light in the form of either glowing or a flame. A gas lighter is a firestarting mechanism used to ignite gas stoves which do not have automatic ignition systems. It relies on a physical phenomenon called the piezoelectric effect to generate an electric spark, which ignites the combustible gas from the stove burner.
