There are two typical alignments which can be implemented in a straight-forward manner. Either the sensor PCB is located co-planar to the plane of rotation for the pivoting magnet, or the PCB would be installed with the sensor parallel to the plane of rotation. Both alignments are shown in Common Lever Alignments.While it is possible to orient the PCB freely when using a 3D Hall-effect sensor, this convention will be used for simplicity.

In many instances co-planar installation will require a larger system footprint. For this reason, a parallel installation will be explored in the following example to maintain a minimal design size within a turn indicator stalk.

Another consideration to account for is the range of travel for the lever. Common automobile applications are shown in Lever Motion Types. Omni-directional lever, similar to what might be experienced implementing a e-Shifter Design using a traditional lever is only able to rotate about a single axis. Steering Column Levers, such as a turn indicator or windshield wiper control, are typically able to tilt bi-directionally supporting two axes of rotation.

While not in use, the turn indicator resides at a center position, but at any time the lever can be pulled toward the driver to toggle the flash-to-pass function. This flash-to-pass function will temporarily enable the high beam headlights until the driver releases the control. This example will demonstrate the retro-fit of a production turn-indicator module using a single Hall-effect sensor shown in Turn Indicator Stalk.
