The invention relates to a charging plug for connection to a charging socket of a device which is intended to be charged, for example, a motor vehicle which is at least partially driven by electrical energy, or a device which provides charging energy. In order to prevent the charging plug from prematurely becoming defective as a result of corrosion or electro migration, there is provision according to the invention for a switching device of the charging plug to be arranged partially inside and partially outside an enclosed conduction chamber.
