Show transcript
Switches play an important role in our lives because they allow us to control the flow of electricity to appliances.
Switches can turn a circuit off by making a gap so electricity cannot flow.
Traditional switches work by making a pair of conductors touch each other or separate from each other.
Engineers have created innovative switches which are sensitive to human touch.
Switches for simple circuits can be created from a range of everyday conductors and insulators.
