摘要

A magnetic catch for drawers, doors and other opening systems has two permanent magnets with one on the door and one on the fixed frame. One magnet is movable between two settings; one attractive setting to hold the item closed and one repulsion setting to open the item. An alternate design has three magnets, with two fitted to one mounting with opposite polarity and with the third magnet on a movable mounting. The strength and size of the magnets is chosen to match the application.
