Electromechanical Timer Teardown

This basic electromechanical timer was installed in a low voltage landscape lighting transformer.  It lasted a couple months short of 10 years.  I opened it up to see and show how it was designed and why it failed.  The clock motor was still working.  The contacts got eroded enough over the years that they were no longer closing.

A good example of simple and low cost electromechanical product design.
