Factory pattern is the right pattern here?

I have a requirement where a base class method needs to be sub-classed further. There is a need to register the class object. And depending on configuration, I will decide which class to instantiate.

class Base {
    Base () { }
    void methodOverride() { // do something; }
}

class Derived1 extends Base {
    Derived () {
        super();
    }

    void methodOverride() { // specialize }
}

class Derived2 extends Base {
    Derived () {
        super();
    }

    void methodOverride() { // specialize }
}

class SelectorFactory {

    Base createClass( int type) {
        switch (type) {
          case DERIVED_1:
             return new Derived1();
          case DERIVED_2:
             return new Derived2();
          case BASE:
             return new Base();
        }
    } 
}

public static void main(String[] args){
    // read configuration
    int type = config.getIntType();

    SelectorFactory factory = new SelectorFactory();
    someRegisterMethod( factory.createClass() );
}

Question: 1. Do you think there is another way to implement this which would be recommended? Is this the best use of this design pattern?
