Wiring two normally open limit switches in series to control two cylinders implements which logic operation?

Explanation:
Two normally open limit switches wired in series behave like an AND gate. Since each switch is open by default, the circuit isn’t complete unless both switches are actuated and closed. Only when both are closed does current have a path to energize the cylinders, so the output is true only when both inputs are true. If they were wired in parallel, the output would be true if either switch closed (OR behavior). XOR would require a more complex arrangement and is not produced by simple series or parallel wiring of identical normally open switches.
