The blog is dedicated to identifying the most common switch-related issues in older homes. It also describes the stylish and safe solutions given by modular switches.

 

The Common Switch Issues in Old Homes

Older homes come with outdated wiring systems, insufficient electrical capacity, or faulty breaker panels are a few common issues. The most common problems in electrical switches are given below

 

Cracked Switch Plates

With time, traditional switches get cracked, worn, or even chipped at the corners. It is not only an awkward scene to the eyes, but it's also dangerous. It is important to repair broken plates as they can expose internal wiring.

 

Loose Connections and Flickering

The common old electrical switches get loose due to loose internal connections. Not only do old electric switches, rockers, or old toggle switches lead to electrical fires or overheating. Modular switches remove all these issues.

 

Unsafe Materials

Most of the old switches have been made with poor-quality plastic or bakelite, which can be degraded over time. These materials may even conduct electricity, if cracked or become brittle in some cases.

 

No Aesthetic Appeal

Modular switches have an amazing and elegant appeal. On the other hand, old switches often clash with modern interiors. Metal screws on display, yellowed switches, and clunky designs stand out against painted sleek and walls.

 

Lack of Child-Safety Features

If we have old switches, then we may have to forget child-safety features, child-proofing, and protective shutters. Old switches make them unsafe in homes with young children.

 

Frequent Malfunctions

Due to a lack of standardization and wear & tear, the switches in old homes fail. It is also not possible to replace just one switch; a large portion of the board has to be replaced. Rewiring a large portion of the board for one switch is costly and time-consuming. 

 

No Extra Functionalities

What is common in electrical switches that are found in old homes? They can just do one thing: switch on or off. Smart switches or modular switches can do a lot more. For example, night lamps integrate USB ports, dimmers, or smart controls, which are now essential in modern living.

 

What does common mean in electrical switches? They have a shared connection point for the incoming power source and can be switched to other terminals depending on the switch’s position. On the other hand, modular switches are modern switches that offer a high level of scalability, customisation, and advanced features. Modular switches offer both functionality and aesthetics in mind. You get customised, sleek, and safe solutions, unlike traditional switches discussed above. Take a look at how modular switches address each of these common issues of old electric switches.

 

No Flickering Lights

Modular switches have superior internal build quality and spring-loaded contacts. It ensures consistent contact. Hence, reducing the chances of loose connections or sparks. So, there would be no unexpected power loss and flickering lights.

 

Shatter-Resistant Plates

Say goodbye to yellowed plastic and cracked corners. Modular switch plates are made from shock-proof, scratch-resistant, fire-proof ABS plastic. So, there is no chance of getting a shock when you have installed modular switches in your place.

 

Clean Design

Modern switches are not only available in common feed electrical switch colours. You can choose different colours and even match them to your wall color!

 

High-Quality, Non-Conductive Materials

Modular switches use non-conductive, long-lasting materials, unlike the fragile bakelite switches of the older times. It helps to prevent current leakage even if damaged. You even get flame-retardant versions of modular switches at some companies, like Diamond India and achieve extra peace of mind.

 

Modular switches have hidden screws and safety shutters that make them safe for kids. A common concern with old electrical switches was that kids could poke into plug holes, which is solved by shutters in modular switches.

 

Why You Shouldn’t Delay Switch Upgrades?

Many homeowners delay upgrading old switches, thinking, “If it still works, why replace it?” But functioning switches can still be unsafe. If the switch feels loose, sparks, or heats up, it may still be hazardous to keep on waiting. Sometimes, many older switch systems are incompatible with modern appliances, leading to overloading and inefficiency. Delaying switch upgrades can result in appliance damage, short circuits, and fire hazards. Hence, a lot of expenditure is waiting for you if you do not upgrade your traditional switches.
