Struthers-Dunn 21 Series – Traffic / Transfer Relays

The 21 series flash transfer relays have a proven industry record of reliability. Their rugged design has allowed the products to be plugged in and left, for years of service. Recent changes in lighting techniques from incandescent to LED have prompted us to respond with a redesigned relay better suited for the low currents of LED lighting, but equally usable with tungsten lamps.

Customer Testimonials

"I was at my wits end. I looked all over for this one part. I figured I would make one last call to Universal. It turns out hard to find parts are their specialty. The on-staff engineer found what I needed and they were able to ship same day. From now on UES will be my first call, not my last." - T. Smith
"Very easy company to do business with. Great customer service. My company has been a customer for ten years." - P. Morgan
