Which element describes two or more normally closed switches in series?

Explanation:
Two normally closed switches in series behave like a NOR gate. Each NC switch is closed only when its controlling signal is off (false). When you put them in series, the current path exists only if both inputs are false, so the output is true only when neither input is true. If either input goes true, its NC contact opens and the circuit is broken, making the output false. That exactly matches the NOR behavior: true only when all inputs are false. So two or more normally closed switches in series describe NOR.
