Understanding Light Switches and Their Mechanisms

What is the main topic introduced at the beginning of the video?

• The installation process of light switches

• The internal mechanism of light switches

• The history of light switches

• The different types of light bulbs

What happens when a basic light switch is flipped to the ON position?

• The circuit closes and the light turns on

• The circuit opens and the light turns off

• The circuit remains unchanged

• The light bulb is removed

What component ensures the toggle switch stays in the ON or OFF position?

• The face-plate

• The central spring

• The plastic housing

• The metal contact bar

What is the role of the face-plate in a light switch?

• To store electrical energy

• To act as a switch

• To conduct electricity

• To provide a decorative cover

What is the purpose of the metal bracket in a light switch?

• To attach the switch to the electrical outlet box

• To change the light bulb

• To provide a decorative element

• To store electrical energy

How do three-way switches differ from basic light switches?

• They do not require wiring

• They are used only in commercial buildings

• They have a common terminal and two traveler terminals

• They have a single terminal

What is required for three or more switches to control a single light?

• A single three-way switch

• One or more four-way switches

• A special type of light bulb

• Multiple basic switches

What happens when the toggle of a four-way switch is flipped?

• The light bulb changes color

• The switch becomes inactive

• The path of electricity is reversed

• The light bulb is removed

What is the main safety advice given in the conclusion?

• Install light switches in every room

• Use only branded light switches

• Do not install light switches unless you are knowledgeable

• Always use LED bulbs
