Top 10 Brands and Manufacturers of General Purpose Realy

Some 189 years ago (in 1835), Joseph Henry manufactured the first general purpose relay.

It was an electromagnetic relay, a key component in early telegraph systems.

This small invention revolutionized electrical control systems. That simple relay has evolved into advanced, more durable devices.

Today, you need a general purpose relay whenever and wherever you need a stable and efficient operation for ANY electrical system. 

These devices are widely used in various applications, from controlling motors and equipment on industrial production lines to managing lighting and air conditioning in building automation.  

In this article, we’ll explore the top 10 general purpose relay manufacturers and brands worldwide. Read till the end, as it will help you select the right brand/manufacturer next time.
