Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the classification?Switches are broadly classified into manual (user-operated) and automatic (signal-operated) types
2. What is the solid-state advancement?Transistors and other semiconductor devices act as high-speed, non-mechanical electronic switches
3. What is an electrical switch?An electrical switch is a device that can open or close a circuit, letting electricity flow or stopping it. It works like a simple on/off button for power.
4. How does a switch control electricity?When the switch is closed, it lets current flow through the circuit. When it is open, it breaks the circuit so the current stops.

Electrical Circuit: A complete, closed path that allows electric current to flow, enabling the operation of electrical devices.
Arcing: The flow of electrical current through a gap in a circuit, often producing light and heat, which can damage switch contacts.
Solid-State Switch: An electronic component, such as a transistor, that controls current flow without moving parts, offering high speed and reliability.
