The relay's primary appeal is its ability to do a lesser-switch's bidding but it's capable of so much more. Relays can be wired together to create very useful, simple, and utterly reliable networks.

Consider a relay to be a type of electronic switch that may be turned on and off by a modest electrical pulse. This enables them to control a circuit with a low-power signal or manage several ...

Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and ...

Often a need arise to interface output of the microcontroller with an electromagnetic relay ... Logic 1 (H = 5V) at the input of the optocoupler PC1 (CNY17-1) will switch on the electromagnetic relay, ...

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...
