Abstract
A cooktop appliance includes a control valve, a spark generator, and a spark switch. The control valve includes a rotatable member for controlling gas flow rates to a burner assembly of the cooktop appliance. The spark generator provides a spark to ignite gas in the burner assembly. The spark switch may be mounted to the control valve, and may include a rotor fixedly mounted to the rotatable member. The rotor may be rotatable between an initial position and a first position. In the initial position, the spark generator does not receive electrical power. In the first position, the spark generator does receive electrical power. The spark generator may be configured to introduce a time delay between receiving electrical power and providing the spark to ignite gas in the burner assembly.
