1. A cooktop appliance, comprising:a panel;
an electrical heating element positioned at the panel, the electrical heating element having a first terminal and a second terminal;
a bimetallic switch positioned adjacent the electrical heating element, the bimetallic switch configured for actuating from a first configuration to a second configuration when a temperature of the bimetallic switch exceeds a threshold temperature; and
a first electrical conduit coupled to the first terminal of the electrical heating element, the first electrical conduit configured operating at a first voltage, L1, with respect to ground;
a second electrical conduit configured for operating at a second voltage, L2, with respect to ground; the first voltage L1 is different from the second voltage L2;
a neutral electrical conduit;
a relay coupled to the bimetallic switch, the relay configured such that the relay connects the second electrical conduit to the second terminal of the electrical heating element when the bimetallic switch is in the first configuration, the relay also configured such that the relay connects the neutral electrical conduit to the second terminal of the electrical heating element when the bimetallic switch is in the second configuration.
