yes because its connected to the mains electricity which is energy(i think)
To install a smart light switch in your home, follow these steps: Turn off the power to the light switch at the circuit breaker. Remove the existing light switch from the wall. Connect the wires from the smart light switch to the corresponding wires in the wall. Secure the smart light switch to the wall. Turn the power back on at the circuit breaker. Follow the manufacturer's instructions to set up and connect the smart light switch to your home's Wi-Fi network.
In a series circuit, if one of the light's filiments opens the bulb will go out, but along with that light every other device in the same circuit will stop operating.Think of an electric light circuit, in your home, that is controlled by a switch. When the switch is turned off the light goes out. This is an example of a series circuit where ithe switch is in series with the lamp.
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
When you turn on a light switch you do not have an open circuit.
Its means there is no continuity between point Ato point B. Ex. A light switch : When the switch is off it opens the circuit and electricity does not get to the light, when the switch is on the circuit is closed and the light will turn on.

To install a light switch with an indicator light in your home, you will need to first turn off the power to the circuit. Then, remove the existing switch and connect the wires to the new switch, making sure to match the correct wires. Finally, secure the new switch in place and turn the power back on to test the indicator light.
A switch simply opens a circuit, stopping the flow of electricity. For example: a simple circuit would be two wires from a battery, one of which goes to a switch, and the other goes to a light bulb. A third wire goes from the other side of the switch to the other conductor of the light bulb. With the switch closed the circuit is complete and the light goes on. Open the switch and the circuit is broken and the light goes off.
The purpose of the common wire in a light switch circuit is to provide a return path for the electrical current to complete the circuit and allow the light to turn on or off when the switch is toggled.
A simple circuit containing a light switch in the on position is a closed circuit. In a closed circuit, electrical current can flow freely, allowing the light to illuminate. If the switch were in the off position, it would create an open circuit, interrupting the flow of electricity and turning the light off.
To install a dimming light switch in your home, first turn off the power to the light switch at the circuit breaker. Remove the existing switch and disconnect the wires. Connect the wires to the new dimming switch according to the manufacturer's instructions. Secure the switch in place and turn the power back on to test the dimming function.
A switch is placed in an electrical circuit in order to place a gap when the switch is off, so the circuit is broken. When the switch is on, the circuit is complete and the electricity can flow round the circuit.
