Cooktop appliance having a reignition spark module

A cooktop appliance, comprising:

• a control valve having a rotatable member for controlling gas flow rates to a burner assembly;
• a spark generator configured to provide a spark to ignite gas in the burner assembly;
• and
• a spark switch mounted to the control valve, the spark switch comprising:
• a rotor fixedly mounted to the rotatable member, the rotor rotatable to at least a first position and a second position, the rotor comprising a first cam and a second cam, the first cam and the second cam each extending radially outward from an exterior surface of the rotor, the first cam and the second cam each extending circumferentially along the exterior surface of the rotor, wherein the first cam and the second cam are circumferentially spaced from one another along the exterior surface of the rotor;
• a first switch movable between an open position and a closed position;
• and
• a second switch movable between the open position and the closed position,
• wherein when the rotor is in the first position, the first switch is in the closed position, the second switch is in the open position, and the spark generator receives a first electrical current from a power supply via the first switch, and
• wherein when the rotor is in the second position, the first switch is in the closed position, the second switch is in the closed position, the spark generator receives the first electrical current via the first switch, and the spark generator receives a second electrical current from the power supply via the second switch.
