Electrical products work by using circuits and switches. Circuits allow electricity to flow through - and so power - bulbs, motors and buzzers. Switches are used to control circuits. They can break a circuit - and so switch bulbs, motors and buzzers off - or complete a circuit - and so switch them on again. Many products work by using electricity.
