    Abstract: A protective circuit arrangement for an infrared radiant-type cooking assembly including a frangible utensil-supporting cover plate of infrared transmissive material with underlying heater blocks in contact with the cover plate and having an open-coil uninsulated resistance element supported on the heater blocks in spaced relation to the plate. A conductive stripe located around the periphery of the cover plate is connected in the circuit having an electronic switch arrangement for sequentially open circuiting the powerlines to the cooking assembly should breakage of the cover plate occur to obviate any shock hazard.
