In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit ...

How many remote controls do you have in your home? Don’t you wish all these things were better integrated somehow, or that you could add remote control functionality to a random device? It’s a common ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...

What is an automotive relay? In simple terms, an automotive relay is a small cube shaped electronically operated electromechanical switch. It uses an electromagnetic device to mechanically maneuver a ...

Body biasing and self-assembled molecular coatings enable 50-mV operation of ultra-small mechanical relays for low-power digital computing. For decades, the electronics industry has relied on scaling ...

Researchers at the University of Bristol have come up with a new type of nanoelectromechanical relay to enable reliable high-temperature, non-volatile memory. The work, which is reported in Nature ...
