The thermocouple is just a safety device which allows the gas to flow. When you push the red buitton down, you are opening a valve which is held open by an electromagnet powered by the small current put out by a heated thermocouple. The gas valve actually opens and closes the main burner, and it has a probe which fits in to the tank.
