The park brake switch is in the same place for all 2100 and 2300 and 2500 combines. The switch on the overhead console is for emergency park brake release, and is used in conjunction with the brake pedal.
Applying the park brake at speed does bring the combine to a rapid stop, enough to cause injury if unlucky. Keep in mind that the switch has a shroud around it preventing it from accidental knocks.
