In this chapter, the authors study switches, relays, connectors and computer hardware components. All the switches therefore, have fixed and moving contacts. The moving contact moves and makes or breaks the connection. The switches may be Manual Switches, Sensing Switches and Electrically operated switches (or relays). The examples of sensing switches are float switches, limit switches, proximity switches etc. Types of Relays: Electromagnetic relay, Latching relays, Solenoid relay, Dry reed relay, Wet reed relay, Stepping relay and Thermal Relay. Connectors have been one of the major causes for poor reliability of electronic equipment. It is not because the connector quality is bad but because not enough thought is given in the selection and application of these components. Hardware components are classified into three categories: Input Devices, Output Devices and Storage Devices. Relays consisting of electronic components are called solid state relays. Connectors may be: one piece edge connector, two piece edge connector, co-axial connectors etc.
