Manual Changeover Switch

Manual Changeover Switch Assemblies (MCO) are designed for permanent and temporary installations, to switch from a permanent mains supply to a stand-by generator (or alternative mains supply) should the permanent mains fail. Upon restoration of the permanent supply, the switch can be manually changed back to permanent mains power. They are a simple, cost effective method of providing back-up power to installations where a loss of supply for a short duration is acceptable.
