A1
B3
C4
D6
AI Explanation
The correct answer is B) 3. The schematic symbol for a normally closed float level switch is represented by option B) 3 in the illustration EL-0059. This is the correct answer because a normally closed float level switch is a type of switch that is closed when the liquid level is at or below the switch's set point, and opens when the liquid level rises above the set point. The other answer choices do not represent a normally closed float level switch. Options A) 1 and D) 6 may represent other types of electrical components, but not a normally closed float level switch. Option C) 4 appears to be a symbol for a different type of switch or control device.
