Ford Transit Fuel Switch (Patent US20110073420)

Non-Locking Pressure Switch designed for Ford Transit (Europe) fuel switch while working for Engineered Products - FilterMinder
Utillity Patent Granted:
https://patents.google.com/patent/US20110073420
Managed all Engineering Design functions and customer communications supporting European Sales Group.

Responsible for Design and Testing of all design changes over the history of the product.

Switch started out in production as a vacuum switch with tight calibration targets and strict quality checks.

After asking the customer probing questions about system details I proposed changing to a pressure switch design to improve response time, and time to failure.
This improved first time through quality rejects from 20% down to 0%.
