Question
Identify the odd one out



Hint:
An electric switch is a device that is used to open or close an electric circuit.
The correct answer is: 
The switch is the odd one out.

- The loads, batteries, generators, and switches are the parts of a circuit.
- The switches are used to interrupt or start/induce a current flow in a circuit.
- When the switch is off, the flow of current in a circuit is interrupted and the circuit will break.
- The switches interrupt the electron flow in a circuit.
