The wall switch is a common electrical device that enables people to have control over the electrical current of a circuit. Wall switches make it possible to turn the lights or other appliances on and off, by pressing the physical switch panels or remote control. A wireless switch uses wireless compatibility to power light fixtures throughout your home. There are more wireless smart switches that can be controlled by APP, smartphone, smart home hub, smart button and more. This eliminates many safety concerns that often come with wall switches, and also makes for a more convenient experience by controlling the lights from the palm of your hand. To install smart wireless switches in a house that doesn’t have a neutral wire, we should either implement a rewiring, or a no-neutral wire-designed smart wireless switch is required.
