     Electrical Contact Spring Test Fixture

The building of our design was done in the machine shop at FAMU/FSU College of Engineering.  

Pictures of this are shown below.

Throughout the building process changes to the design were made.  The small size of the testing fixture was the main culprit in these changes.  

This is a picture of the finished testing fixture.
