Abstract
A hinge for a door pivotally mounted on a cabinet is provided with a switch for activating an electrical circuit within the cabinet. The switch has a reed sensor mounted within a base of the hinge for activating the electrical circuit and a magnetic actuator affixed to a pivot pin of the hinge for moving relative to the reed sensor to activate the reed sensor between a normally open position deactivating the electrical circuit when the door is closed and a closed position activating the electrical circuit when the door is open.
Claims4
A hinge for a door pivotally mounted on a cabinet, said hinge comprising
- a housing for securement to the cabinet, said housing having an outwardly projecting base with a first cam surface thereon;
- a post for securement to a door, said post having a pivot pin pivotally mounted in said base for movement of said post between a closed position and an open position and a second cam surface in mating engagement with said first cam surface for moving said post axially of said pivot pin relative to said base during pivoting of said pin in said base;
- and
- a switch for activating an electrical circuit within the cabinet, said switch having a reed sensor mounted within said base for activating the electrical circuit and a magnetic actuator affixed to said pivot pin for moving therewith relative to said reed sensor to activate said reed sensor between an open position deactivating the electrical circuit with said magnetic actuator in alignment with said reed sensor and opposite said reed sensor and a normally closed position activating the electrical circuit with said magnetic actuator out of alignment with said reed sensor and out of opposition to said reed sensor.
