Relays come in a variety of form factors, styles and technologies. Depending on your application, only one relay type may be suitable. In other cases, multiple relay types may be appropriate. By understanding the strengths and weaknesses of the different relays, you should be able to pick the one that is best suited for the job at hand.

The most common types of relays used in ATE applications are:

  • Electromechanical Relays
  • Reed Relays
  • Solid State Relays (SSRs)
  • FET Switches

This white paper explains how these relays operate, and identify their relative strengths and weaknesses.
