Abstract
A latch assembly, including: at least one moveable component rotationally mounted to the latch assembly; a magnet secured to the at least one moveable component; a hall effect sensor remote from the magnet; and a metal trace operably coupled to the hall effect sensor and configured to be magnetized by the magnet as the at least one moveable component rotates.

An assembly for detecting the position of a moveable component of a latch assembly, comprising:
- a magnet secured to the moveable component, the moveable component being rotationally mounted to the latch assembly;
- and
- a hall effect sensor mounted on a printed circuit board remote from the magnet;
- and
- a metal trace mounted on the latch assembly, the metal trace in communication with the hall effect sensor, the metal trace being configured to define at least two separate portions that are separately magnetized by the magnet as the moveable movable component rotates in a first direction from a first position to a second position, wherein the at least two separate portions are configured such that the magnet can be located between the at least two separate portions wherein the at least two separate portions are not magnetized by the magnet.
An assembly for detecting the position of a moveable component of a latch assembly, comprising:
- a magnet secured to the moveable component, the moveable component being rotationally mounted to the latch assembly;
- a first hall effect sensor mounted on a printed circuit board and in communication with a first metal trace in a position remote from the magnet;
- a second hall effect sensor mounted on the printed circuit board and in communication with a second metal trace in a position remote from the magnet;
- wherein the first metal trace is magnetized by the magnet when the moveable movable component is in a first position and the second metal trace is magnetized by the magnet as the moveable movable component rotates in a first direction from the first position to a second position, wherein the first metal trace and the second metal trace are not magnetized by the magnet when moveable movable component is located between the first position and the second position.
A method for detecting movement of moveable component of a latch assembly, comprising:
- rotationally mounting the moveable component to the latch assembly;
- securing a magnet to the moveable component;
- locating a first hall effect sensor remote from the magnet, the first hall effect sensor being operably coupled to a latch controller;
- operably coupling a first metal trace to the first hall effect sensor;
- locating a second hall effect sensor remote from the magnet, the second hall effect sensor being operably coupled to the latch controller;
- operably coupling a second metal trace to the second hall effect sensor;
- wherein the first metal trace is magnetized by the magnet when the moveable component rotates is in a first position and the second metal trace is magnetized by the magnet when the moveable movable component rotates in a first direction from the first position to a second position, wherein the first metal trace and the second metal trace are not magnetized by the magnet when the moveable component is located between the first position and the second position.
