Key Stage 1
Meaning
A switch is something you can use to turn things off and on.
Key Stage 2
Meaning
A switch is a component in a circuit that can connect or break the circuit to control whether electricity flows.
About Switches
- A switch is anything that breaks a circuit.
- A switch turns things off by breaking a circuit.
- A switch turns things on by connecting the wires to complete the circuit.
- A circuit should always have a switch in it so it can be turned off if anything goes wrong.

Key Stage 3
Meaning
A switch is a component in a circuit that can connect or break the circuit to control whether electricity flows.
About Switches
- A switch is anything that breaks a circuit.
- An 'open' switch prevents electricity from moving around the circuit.
- A 'closed' switch allows electricity around the circuit.
- A switch is a useful safety device in a circuit so that the current can easily be stopped. This prevents components from getting too hot and prevent electrocution from a damaged wire.
