This design may work in a project we are looking at doing. I have some questions.
What is the part number (PN) and manufacturer of the barrel magnet used?
Referencing page 8 of the document. What is the PN and manufacturer of the dual package SPDT relay used?
Are there additional pictures of the barrel magnet and how it is mounted and close the hall sensors are to it?
How is the sunroof OPEN and CLOSED detected? Difference in current draw?
