    Measure Relay's Contact Resistance To Diagnose Failure Even the best Relays can fail at some point, but what causes them to fail? Conventional wisdom places the blame on worn out contacts. Every electromechanical Relay has a finite number of cycles it can endure before the contacts call it quits.

    Relay Contact Resistance Contact resistance is a crucial electrical characteristic. The resistance between the contact terminals determines the Relay's ability to carry current. The contact resistance is subject to change during the life of the Relay. Based on lab investigations and testing, abnormal contact resistance has often been found with the following conditions:
