The mechanical timer serves as a backup in case of electrical failures because it operates independently of any electrical power source. Unlike digital timers that rely on electricity to function, the mechanical timer's movement is entirely driven by a self-contained mechanical mechanism, such as gears and springs.
In the event of an electrical failure or power outage, the mechanical timer continues to measure and display the cooking duration accurately. Its self-sustained operation ensures that users can still set and monitor the cooking time without relying on electricity.
This reliability makes the mechanical timer a dependable backup solution, ensuring that cooking cycles can proceed as planned even when there are electrical disruptions or power failures.
