Which code is the Normal switch control relay?

Explanation:
In this signaling coding system, the relay codes use a letter to indicate the state or function, with the prefix N typically signaling something about the Normal (default) condition. The Normal switch control relay is identified by the code that uniquely pairs the Normal state with the switch-control function, which is Nwz. This code designates the relay whose role is to maintain or indicate the switch in its normal position within the interlocking logic. The other codes don’t represent that specific function in this scheme, so they don’t match the Normal switch control relay.
