Figure 4-3. Housing Button Cover
The dial attachment is a small round piece that sits in the hole of the button surface. The main purpose is to
provide a spot for the dial to clip into. The dial attachment needs to be fixed to the button surface with glue to
ensure that it does not move when using the button.
Figure 4-4. Button Cover with Dial Attachment
The dial is designed to clip onto the dial attachment with a spring sitting between the two. The dial also has a
small hole that the magnet gets glued into. This allows for the magnet to sit directly above the TMAG5273 for
best rotational sensing measurements.
