Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to ...

The critical role of snubber circuits in minimizing ringing and overshoot. How snubber circuitry is evolving to adapt to trends in power electronics, like the rising interest in wide-bandgap ...

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

Electromechanical components including pushbutton switches, rocker switches, and illuminated tact switch buttons for power circuits and interfaces by Marquardt are available from TME. The components ...

This simple and cost-effective ding dong electronic doorbell circuit is based on IC 8021-2. The IC has an in-built circuitry to produce ding dong sound each time its pin 3 is pulled low. The sound is ...

In physics and materials science, the term "spin chirality" refers to an asymmetry in the arrangement of spins (i.e., the intrinsic angular momentum of particles) in magnetic materials. This asymmetry ...

Modern electronics are a far cry from what Michael Faraday, the pioneer of electrical gadgetry, can ever have imagined possible. But he’d surely be pleased, if only because the magnet, the component ...

Note: This article references the 2017 NEC because the Philadelphia area — the jurisdiction where this author teaches and works— is still operating under that version of the Code. Electrical switches ...
