【Abstract】This article mainly analyzes the common failure types of automotive relays. Firstly,starting with an overview of the basic theoretical knowledge of relays,such as their basic structure,working principles,and selection principles,this paper summarizes the common failure types of automotive relays,and verifies the fault problems with practical cases. It is hoped to provide some reference for the design of automotive relays.
