Can I store a reference to a constructor in C#?

 switch(inputType)
 {
     case InputType.Pointer: return new PointerInput(); break;
     case InputType.Keyboard : return new KeyboardInput(); break;
     case InputType.Gamepad: return new GamepadInput(); break;
     default: Debug.LogWarning("No input type set. Using defaults."); return new PointerInput();
 }

This switch case gives me a warning "unreachable code detected", which makes perfect sense to me. So is there a way that I could store my constructors (new PointerInput() etc.) like a variable und write a better switch statement like so:

 SomeType constructor;
 
 switch(inputType)
 {
     case InputType.Pointer: constructor = new PointerInput(); break;
     case InputType.Keyboard : constructor = new KeyboardInput(); break;
     case InputType.Gamepad: constructor = new GamepadInput(); break;
     default: Debug.LogWarning("No input type set. Using defaults."); constructor = new PointerInput();
 }
 
 return new constructor();
