Changeover Switch

Changeover Switches are switch-disconnectors with independent manual operation intended to be used in low voltage distribution circuits and motor circuits. They are capable of making, carrying and breaking current under normal circuit conditions which may include operating overload conditions and also carrying for a specified time currents under specified abnormal circuit conditions such as those of short circuit. Four pole changeover switches are required in a three phase four wire power system for safe and foolproof transfer of power from normal supply to auxiliary or emergency supply and vice versa. On load changeover switches are used in lighting circuits or motor circuits, where ever continuity of supply is necessary, for switching to an alternate source of supply from main supply and vice versa. They are switch disconnectors with independent manual operation for use in Low Voltage Distribution circuits.
