- A piezo-electric ignition is a form of ignition that is used to ignite some gas burners.
- It is not powered by actual electric current but derives its voltage from high pressure.
- It works under the Piezo-electricity concept which refers to accumulated voltage formed by specific materials in response to high pressure.
- Pressing the switch/button introduces immense pressure on piezo-electric material such as a Quartz crystal.
- Pushing the button drives a spring-loaded hammer toward the crystal.
- The pressure exerted on the crystal releases a high voltage which then sparks/ignites the gas.
- Piezo-electric ignition systems are usually fitted with switch buttons, levers, or a knob in the case of a gas burner.
- The igniting voltage is usually produced once at each turn of the knob.
