Describe the contact symbol.
What will be an ideal response?
Another very common symbol used on control schematics is the contact symbol. The symbol is two parallel lines connected by wires. The normally open contacts are drawn to represent an open connection. The normally closed contact symbol is the same as the normally open symbol with the exception that a diagonal line is drawn through the contacts. The diagonal line indicates that a complete current path exists.
