Plastic switch off the ignition lock???

Was working on my 1973 Dodge Dart Swinger the other day. Everything was good and motor was starting. Then went to start it later and Nothing. Pulled the steering wheel and found a white plastic piece with a switch on it that the ignition lock hits when you turn the key. Does anyone know what the part name or number for this is and if you can order one anywhere??? View attachment 1715107076

That is the buzzer switch for when you leave the key in the ignition, but it shouldn't cause the engine to not start.
Chrysler Part 2947488 key buzzer switch.
