... coding the alarm the basic alarm circuit. This can be used to challenge more able pupils at KS3 or incorporated within the design brief for older pupils. The concept is very simple and a coded alarm does not require an on/off switch to effect the reset. Study the extension to the circuit on page 8. ...

Switch
In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.
