Smart switch provides us with many different features

Smart switches are a direct replacement for our traditional built-in switches. They get installed using existing in-wall back boxes and provide a solution for upgrading current ones that we use every day, (usually for built-in lights). We may not want or need to upgrade every switch in our house, but there are probably a few very frequently used ones, that would be perfect for a smart upgrade. The best ones work as a regular light switch, but also provide us with new ways to control our home lighting and switch wired devices like waste disposal units and fireplaces, even the ceiling and bathroom fans throughout your home. Very commonly used one is also a smart TV switch.

How do they work

Remote control features were added to light switches years ago, and it is all thanks to the radio frequency and infrared technologies.

To upgrade our light switches with a remote control functionality and connect them to our Smartphone, modern products are using Wi-Fi or Bluetooth technology, which makes them “smart” devices and gives them an array of capabilities, including app or voice control.

Some of the switches may have extra buttons for more specific light control, while others come with additional sensors or light indicators. They also often have their own smart device apps that we can download and use it to control them from a mobile device. This means we don’t technically have to use the switch at all. For example, if we are not at home, we could turn on our lights at home so that people think someone’s there. There is also a function of dimming, which depends on the bulbs we are controlling however, if they are compatible, most smart switches provide dimming options for changing the brightness of our lighting.

Most smart switch apps allow us to create schedules for our lighting, an increasingly common way of saving energy and providing some extra convenience around the house. For instance, we can program our lights to come up as we are heading home from work, or set a vacation program that only keeps a couple lights on at night for safety.

Wireless or remote light switches

A wireless switch commands a light or home appliance to turn itself off or on. There are different ways of communication between the switch and the fixture:

When it is about a radio transmission, a radio receiver is typically wired or screwed into a fixture or device, wired or otherwise connected to the electrical system of the building, or plugged into an outlet. The radio receiver's memory is programmed by any number of means, to respond to certain selected "switches" or remote control transmitters.

Using the existing power lines, firstly a receiver is plugged into an outlet and a then a device into the receiver. The plug-in receiver gets programmed to the switches. Some devices are hard wired into the ceiling light fittings, making for a hidden system.

There are two main pieces to a wireless light switch set up, the transmitter and a receiver. These two are the only things that are needed in turning a standard light fixture into a wireless manifestation of the same function. The transmitter in a remote light switch needs to receive its power from another source. Some solve the issue through batteries, the problem though, is that they run out and there is no way of knowing when it is going to happen. The other two possibilities are solar power and kinetic energy. Solar power gets used primarily in transmitters that are hands free. The final possibility is kinetic energy. For that purpose, the manufacturers design little modules inside of the switch, which makes some resistance when a user presses the transmitter. The force against this resistance is what creates a spark of energy, just enough to send a signal.
