Why is a switch important in an electric circuit ?

Explanation

### Step-by-Step Solution:

1. **Understanding the Electric Circuit**: An electric circuit consists of various components, including a power source (like a battery), conductors (wires), and loads (like bulbs). The circuit allows electric current to flow through these components.

2. **Role of the Switch**: A switch is a device that can open or close an electric circuit. When the switch is closed (ON position), it completes the circuit, allowing electric current to flow. Conversely, when the switch is open (OFF position), it breaks the circuit, stopping the flow of current.

3. **Current Flow**: For electric current to flow, there must be a complete path (closed circuit). When the switch is closed, the circuit is complete, and the electric current can flow to power devices like bulbs or motors.
