PUSH BUTTON SPARK IGNITER (SM2

A push-button (also spelled pushbutton) or simply button is a simple switch mechanism to control some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, although many un-biased buttons (due to their physical nature) still require a spring to return to their un-pushed state.

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.
