Solution

Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.

Explanation:

A switch connected in the neutral wire can break the circuit and stop the current, but for safety a switch must always be placed in the live wire. The neutral wire is at zero potential, so the Reason is true, but it does not explain why the switch works.
