Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

A friend once asked about the block of relays pinned to a board behind my car's dash. To him relays were the mysterious little boxes that some cars inexplicably required to operate a horn. More than ...

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 ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

Here’s a MEMS relay with an integrated FET that can handle higher power levels, breaking away from the “low power” moniker associated with MEMS parts. Paul Rako takes a closer look at what makes this ...

Ready-made wiring harness and relay kit makes it easy to add relays to a motorcycle headlight. Adding a relay can improve headlight output, reduce load on switches and allow higher wattage bulbs to be ...
