To determine
The name of the symbol from the given options.
Expert Solution & Answer
Explanation of Solution
The symbol shown in Figure 1 is used in a schematic of control circuits to designate normally open contact.
Two parallel horizontal lines or vertical lines are used to indicate a normally open contact. The normally open contact in a circuit schematic depicts that the circuit is open and no current flow is present.
Thus, the correct answer is “option d. Normally open contact”.
