Which code denotes the normal switch repeater relay?

Explanation:
In signaling codes, a relay or device is labeled with a compact three-letter code that conveys its state and function. The first letter indicates the circuit’s status as normal, and the remaining two letters specify the device type. For a normal switch that acts as a repeater, you need the code that combines the normal state with the switch-related repeater function. That combination is the code for the normal switch repeater relay, which is Nwp. The other codes point to different devices or roles, so they don’t describe the normal switch repeater.
