An Isolator Switch is a switch normally found above the bathroom door. Its only purpose is to let the owner decide if they want the extractor fan to come on or not when they switch the light on in the bathroom.

The extractor fan has to be installed in any new bathroom, Shower Room or W.C in any residential dwelling under the new building regulations so its not just for lofts its now for the whole house.
