Push a button and turn on the television; tap a button and get a ride; click a button and “like” something. The touch of a finger can set an appliance, a car, or a system in motion, even if the user doesn't understand the underlying mechanisms or algorithms. How did buttons become so ubiquitous? Why do people love them, loathe them, and fear them? In Power Button, Rachel Plotnick traces the origins of today's push-button society by examining how buttons have been made, distributed, used, rejected, and refashioned throughout history. Focusing on the period between 1880 and 1925, when “technologies of the hand” proliferated (including typewriters, telegraphs, and fingerprinting), Plotnick describes the ways that button pushing became a means for digital command, which promised effortless, discreet, and fool-proof control. Emphasizing the doubly digital nature of button pushing—as an act of the finger and a binary activity (on/off, up/down)—Plotnick suggests that the tenets of precomputational digital command anticipate contemporary ideas of computer users. Plotnick discusses the uses of early push buttons to call servants, and the growing tensions between those who work with their hands and those who command with their fingers; automation as “automagic,” enabling command at a distance; instant gratification, and the victory of light over darkness; and early twentieth-century imaginings of a future push-button culture. Push buttons, Plotnick tells us, have demonstrated remarkable staying power, despite efforts to cast button pushers as lazy, privileged, and even dangerous.

Circuit control in its simplest form, is the application and removal of power. This can also be expressed as turning a circuit on and off or opening and closing a circuit. Before you learn about the application of circuit control devices, you should know why circuit control is needed. If a circuit develops problems that could damage the equipment or endanger personnel, it should be possible to remove the power from that circuit. The circuit protection devices (fuses and breakers) are not the control devices; these are protection devices that will remove power automatically in event of overload conditions. Circuit control devices allow you to turn the device ON when it is needed and OFF when it is not needed.There are three type of common circuit control devices; switches, relays and solenoids. • Switches, in simple terms is a two piece metal called contacts that touch to make a circuit and separate to break the circuit. Switches can be classified according to the arrangement of their contacts.• Relays are protective, or control, devices, which complete or break an electrical circuit in response to electrical changes in an external circuit.• Solenoids consist of one or more coils surrounding an iron core. The coil(s) and the core are moveable in relation to each other. The axial or rotary movement is a result of the magnetic flux of the coil. It is designed to convert electrical energy into mechanical energy.This 3-hr Quick Book provides general requirements, classifications, installation, maintenance, testing, and application information for circuit control devices, and covers the requirements for switches, relays and solenoids. The course is based entirely on Naval Education and Training Materials (NAVEDTRA 14175), Electricity and Electronic Training Series; Module-3 and covers Chapter 3 titled “Circuit Control Devices”. This course is aimed at students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers and general audience. Learning ObjectiveAt the conclusion of this course, the reader will be able to:• State reasons for providing circuit control devices • List three general types of circuit control devices.• Identify the schematic symbols for a switch, a solenoid, and a relay.• State the difference between a manual and an automatic switch and state the reason multi-contact switches are used.• State the type of switch used to prevent the accidental energizing or de-energizing of a circuit.• State the meaning of the current and voltage rating of a switch.• State the operating principle of a solenoid and describe how to check a solenoid for proper operation.• State the operating principle of a relay and how it differs from a solenoid.
