Switches, plugs and sockets are made of

Options

A. Conductors only
B. Insulators only
C. Semi-conductors covered with insulators
D. Semi-conductors only

Explanation

**Step-by-Step Solution:**

1. **Understanding the Components**: Switches, plugs, and sockets are essential components in electrical circuits. They are used to control the flow of electricity and connect electrical devices to power sources.

2. **Material Composition**: These components are typically made from materials that are good insulators or conductors. Insulators prevent the flow of electricity, while conductors allow it.

3. **Common Materials**:
- **Plastic**: Most switches and plugs are made from plastic, which is a good insulator. This prevents accidental electric shocks when touching these devices.
- **Metal**: The internal parts of plugs and switches, which conduct electricity, are usually made from metals like copper or brass. These metals are excellent conductors of electricity.

4. **Safety Features**: The combination of insulating materials (like plastic) and conductive materials (like copper) ensures that switches, plugs, and sockets are safe to use. The insulating material protects users from electric shocks, while the conductive material allows electricity to flow when needed.

5. **Conclusion**: Therefore, switches, plugs, and sockets are primarily made of plastic for insulation and metal (like copper or brass) for conducting electricity.
