Zündsicherung is a safety feature commonly found in gas appliances, such as gas stoves and heaters. Its primary function is to prevent gas leaks by ensuring that the gas supply is automatically shut off if the flame goes out. This helps to reduce the risk of fire or explosion, making it an essential component for safe operation. The Zündsicherung typically consists of a thermocouple or a flame sensor that detects the presence of a flame. If the flame is extinguished, the sensor sends a signal to the gas valve, closing it and stopping the flow of gas. This mechanism enhances safety in homes and commercial settings using gas appliances.
