Many electrical, as well as electronic gadgets, use different types of relays to function correctly. Depending upon the type of equipment, the most suitable switching methodology needs to be used. In layman’s terms, a relay acts as a switch and changes the state in which a device continues to exist. All appliances including your smartphone, your laptop, and even your air conditioning require specific relaying equipment.

Classifications and categories

Auxiliary relays and protective relays are two of the essential types depending upon the application of the switching system. However, the classification of relays is done keeping in view the principles under which they operate. Solid state relays and electromechanical relays are two of the most prominent ratings. In recent years, the application of hybrid relays has become vital. A hybrid relay is a combination of solid state relays and electromechanical relays. It is the latest addition to the technology. It has all the benefits that an EMR and an SSR can provide.

Improvement is the name of the game

Initially, electromagnetic relays were most widely used on a large number of electronic devices. The operating coil of this type was crucial to the overall operation. With time, many problems erupted because of the wear and tear that electromechanical relays underwent. Even now many electronic devices have electromagnetic relays. But, power consumption is one of the significant issues associated with EMRs.

Manufacturers of electrical as well as electronic gadgets started using solid state relays in place of EMRs. SSRs did not need a lot of energy to operate correctly. At the same time, unlike electromechanical relays, they did not make a lot of noise. But, solid state relays also had a considerable number of demerits.

If the device required more than a hundred amperes of power to function, then solid state relays proved futile. Hence, scientists took measures to combine the positive aspects of electromechanical relays and solid-state relays. Very soon hybrid relays took over the world of electronics leading to the development of high quality and low energy consuming gadgets.

Excellence was never far away

Hybrid relays have the power of EMRs combined with the efficiency of SSRs. The hybrid principle can be used in creating switching systems of different kinds. Thermal relays and reed relays are also popular with many manufacturers of electronic gadgets. However, they can cater to the needs of very few devices. As a result of this, their popularity is nowhere near the efficiency of hybrid relays.

Traditionally, electromagnetic switches were used in a large number of devices. They were prone to a lot of friction and wore out pretty quickly. A lot of maintenance at frequent intervals was needed to make sure that they kept on functioning correctly. Electrical devices which used electromechanical relays consumed a lot of power. At the same time, switching between AC and DC load used to be a time-consuming affair.

How Hybrid Relays Can Simplify Compliance ?

SSRs changed the landscape

The advent of solid state relays was a big step towards the eradication of all problems that were posed by electromechanical switches. But, solid state relays had substantial limitations which prevented their use in most electrical gadgets. If the device needed more than hundred amperes power, the solid-state relays proved to be ineffective. So, engineers continued using electromechanical switches when designing high power equipment.

Necessity is the mother of invention

Since both solid-state relays, as well as electromechanical relays, proved to be deficient in several ways, an optimum solution was always around the corner. As a result, hybrid switches arrived on the scene and made the lives of millions of people across the world more accessible. Hybrid relays make use of elements from both static as well as magnetic switches.

Why Are Hybrid relays practical?

A hybrid of SSRs and EMRs can function even when a lot of power is used by specific equipment. At the same time, hybrid relays can make sure that the switching between loads does not take a lot of time. Unlike Electromechanical switches, they are not prone to friction, and hence they can last for substantial periods without any wear and tear.

Hybrid relays for all times

The best thing about a combination of solid and magnetic switches is that application has widened significantly. Energy consumption by hybrid switches is much less than the power which was used by electromechanical relays. They can work efficiently not only on DC but also on AC devices. But it is crucial that the aptest kind of hybrid relays is used to get the best results.

Wide range of applications

High-quality hybrid switches can be useful even in case of devices that require zero voltage switching. Hybrid switches make very little noise when they operate. As a result, their power consumption is reasonable. It makes them cost-effective. It would be apt to say that, hybrid relays they have all the benefits of solid state relays along with the positive effects of electro mechanical switches.
