As a key part of the relay, the static contact element is responsible for disconnecting or closing the circuit in the circuit. Its processing precision and positioning accuracy are of great significance for improving the service life of the relay and reducing the failure rate. With the development of industrial automation and intelligence, the requirements for the precision and performance of relays and their components are getting higher and higher. Therefore, it is necessary to design a positioning jig for processing a static contact element of a relay.
