Question 18Electricity & Electronics - 1st Asst/Chief

The correct answer is C) 11, which represents a normally closed limit switch in the electrical schematic symbol illustration EL-0059. A normally closed limit switch is a type of switch that is closed (conducting) when the actuating force is not applied, and opens (non-conducting) when the actuating force is applied. This is the symbol typically used to represent this type of switch in electrical schematics and diagrams. The other answer choices do not represent a normally closed limit switch. For example, option A) 6 is the symbol for a normally open switch, while options B) 10 and D) 14 represent different types of electrical components not specifically related to a normally closed limit switch.
