Question 351Electricity & Electronics - Assistant Engineer

The correct answer is C) 8, which represents a normally closed thermostat in the electrical schematic illustration EL-0059. A normally closed thermostat is a type of switch that is closed when the temperature is below a certain threshold, and opens when the temperature rises above that threshold. This symbol is used to represent this type of temperature control device in electrical schematics, as per the standard electrical schematic symbols used in the U.S. Coast Guard Captain's License Examinations. The other answer choices do not represent a normally closed thermostat. For example, option A) 1 represents a single-pole, single-throw switch, which is a different type of electrical component.
