We’ve all built projects that are a rats’ nest of wiring and feature creep, but the best projects in the end are usually those that use a simple solution to elegantly solve a problem.

This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...

Abstract: This paper presents an LC passive wireless sensor for monitoring both humidity and pressure by using a relay switch. The LC sensor system consists of an inductor, two capacitors, and a relay ...

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

It’s more than fair to say that the Nintendo Switch 2 is the current “hot ticket item” in the gaming space right now. After all, pre-orders have been so big that we’re possibly getting set for the ...

Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and how they work in cars. You can still find the articles here (Part I: Why We ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Relays come in a variety of forms, including solid state and electromechanical, which are the more common types. Though there are many different kinds of relays, all of them have the same mechanism. A ...

Your vehicle includes a multitude of electrical components, which are all required to work together in harmony for a seamless experience. These components are responsible for every system, from the ...

The manufacturer of high performance reed relays, Pickering Electronics, has announced its first high voltage surface mount reed relays, known as the Series 219, at Productronica, the world’s leading ...
