How does an oven lighter work?

An oven lighter, often referred to as a piezoelectric lighter, works by generating a spark to ignite gas. When the user presses the button, a spring-loaded mechanism strikes a piezoelectric crystal, creating a high-voltage electrical discharge. This spark ignites the gas emitted from the burner, producing a flame for cooking or heating. The design allows for a safe and efficient way to light ovens and grills without the need for matches or open flames.
