Material choice drives switching performance.

Relays may all look similar from the outside, but what’s inside can make a big difference in how well they do the job.

Relay contacts are the critical components of a relay responsible for opening and closing electrical circuits. There are several different types of materials used to perform this job. Choosing the right one has a major effect on efficiency, lifespan, and ability to handle different types of electrical loads.
