Relays & Switches — Industrial, Mil-Spec & Legacy

Relays and switches fail in service and need exact replacements — coil voltage, contact rating, form factor, and timing specs all matter. When the original relay has been discontinued, the wrong substitute can mean a redesign or a qualification program that costs more than the relay itself. RH Electronics stocks and sources relays and switches across all types and generations, including legacy industrial and mil-spec devices no longer in production.

Common Questions

Can you source obsolete or discontinued relays?
Yes. Discontinued relay families — including legacy industrial contactors and out-of-production mil-spec relays — are among our most common requests. We reach worldwide overstock and excess inventory.
Do you carry sealed or hermetically sealed relays?
Yes. Hermetically sealed relays for military and aerospace applications are in our stock database. Send us the part number and we'll advise on availability.
How do you verify relay authenticity?
Documentation, date codes, and physical construction checked on receipt. For high-reliability applications, we can direct electrical testing through accredited independent labs.
