Abstract
A casing with magnetic latch that is easy to produce and a cover can be quickly opened. The casing has a first magnetic unit and a third magnetic unit respectively mounted in the cover and base. A second magnetic unit is slidably mounted between the first and third magnetic units. When the cover is closed, attraction between the first and third magnetic units holds the cover firmly against the base. When the second magnetic unit is slid between the first and third magnetic units, repulsion between the first and second magnetic units pushes the cover away from the base.

A casing with magnetic latch comprising:
- a base;
- a cover connected pivotally to the base;
- a first magnetic unit attached securely to the cover;
- a second magnetic unit mounted slidably either on the cover or on the base;
- and
- a third magnetic unit attached securely to the base and aligning with the first magnetic unit;
- wherein
- when the second magnetic unit stays away from the first and third magnetic units, an attraction is generated between the first and third magnetic units, and
- when the second magnetic unit slides between the first and third magnetic units, repulsion is generated between the first and second magnetic units and between the second and third magnetic units.
A casing with magnetic latch comprising:
- a base;
- a cover connected pivotally to the base;
- a first magnetic unit attached securely to the cover;
- a second magnetic unit mounted slidably on the base;
- two magnets attached securely to the cover, and the first magnetic unit located between the magnets;
- and
- two metal members attached securely to the base and respectively aligning with the magnets, and the second magnetic unit located between the metal members;
- wherein
- an attraction is generated between the magnets and the metal members, and
- when the second magnetic unit slides to overlap the first magnetic unit, repulsion is generated between the first and second magnetic units.
