When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

I designed this relay circuit to function as a DPDT toggle which is controlled by a momentary switch. I strive to keep my circuits simple with little or no integration (555’s, transistors, etc). The ...

I tested a $15 smart switch and uncovered a $1,500-a-year energy waste in the kitchen ...

Theprevious "Tips" columndescribes some considerations engineers must understand when they choosereed-relay switches for test and measurement applications. Relaycharacteristics and switch topologies ...

An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

Electromechanical relays are like dinosaurs who haven’t gotten the news that they are supposed to be extinct. Instead, they beget new generations, get designed into new applications, and even take ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Pickering’s smallest miniature SIP reed relay with a power rating up to 80 Watts offers alternative to mercury wetted reed relays or electromechanical relays Leading manufacturer of high performance ...
