Abstract
A refrigerator lamp on/off switch housing is mounted in an insulating partition of a refrigerator. The refrigerator lamp on/off switch housing is divided into an upper housing part and a lower housing part. The lower housing part has a first magnet and a first plurality of springs, and the upper housing part has a second magnet and a second plurality of springs. A third magnet is mounted on the upper side of a door of a fresh food compartment, and a fourth magnet is mounted on the lower side of a door of a freezing compartment. A fresh food compartment lamp and a freezing compartment lamp are controlled to be turned on and off by a repulsive force between the magnets and a restoring force of the springs as the doors are opened and closed.
