Fan switch broken

First the power to the cooktop was turned off. Two screws were removed to be able to lift the fan switch holder. The old switch was removed easly because it fell apart. The nuts holding the part in broke as they were removed so they could not be reused. The new switch was put in place however the nuts were too small. I don't know what they were supposed to fit but not these screws. The part was super glued in place. It works perfectly.
