What happens to a circuit when a normally closed contact opens due to actuation of its control input?

A normally closed contact is conducting when the control input is not active, and it opens when actuated. When it opens, it breaks the current path in the circuit, so no current reaches the load and the load de-energizes. This is opposite of a normally open contact, which would close and energize the load on actuation. The idea of the circuit remaining unaffected or latching on would require additional circuit elements or configurations; simply opening a normally closed contact stops current flow.
