Abstract
Apparatus for controlling the temperature of a cooking location of a cooking unit includes a temperature sensor having an outer tube and an inner rod received within the tube and having a different coefficient of expansion, a switch base operatively connected to the temperature sensor and carrying electric contacts actuated by the temperature sensor, and an igniter connected to the temperature sensor and/or switch base.

Apparatus for controlling the temperature of a gas-heated cooking location of a cooking unit;
- comprising:
- a temperature sensor including an outer tube and an inner rod received within the tube, said tube and said rod having different coefficients of thermal expansion;
- a switch base operatively connected to the temperature sensor and carrying electric contacts actuated by the temperature sensor;
- and
- an igniter connected to one of the elements selected from the group consisting of temperature sensor and switch base, said igniter circumscribing the temperature sensor.
