When evaluating a Gas Switch Ignition Factory, you must prioritize material durability and electrical precision. Key specs include high-temperature resistant plastics (PPS or PA66) for the housing, silver alloy contact points to ensure conductivity and prevent oxidation, and a rated voltage/frequency (typically 220V-240V or 110V-120V) that matches your target market. Ensure the spark energy output is sufficient for rapid ignition (usually >10mJ) and that the switch can withstand at least 30,000 to 50,000 cycles of operation.
