|SPST ( SINGLE POLE, SINGLE THROW) SWITCH|
Method of actuation: Mechanical switch. It must be touched to activate.Number of poles and throws: SPST ( Single pole, single throw). This is an ON/OFF switch, when the switch in the below circuit is ON or closed, then the current flows through the two terminals and the bulb in the circuit will blink. When the switch is OFF or open, then the current doesn’t flow through the two terminals.
Operation and construction: Push button
An electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.
ELECTRONIC COMPONENT FOUND
Switch in a fuse box, light bulb, plug adaptor
Mechanical switch: must be activated physically, by moving, pressing, releasing, or touching its contacts.These are used for connecting one line to one of many lines.Examples of these switches are range selectors in electrical metering equipment, channel selectors in communication devices and band selectors in multi-band radios.It consists of one or more moving contacts (knob) and more than one stationary contact.
ELECTRONIC COMPONENTS FOUND
Rotary switch in a lamp
|PUSH BUTTON SWITCH|
It is a momentary contact switch that makes or breaks connection as long as pressure is applied (or when the button is pushed).Generally, this pressure is supplied by a button pressed by someone’s finger.This button returns its normal position once the pressure is removed.It consists of stationary and movable contacts, of which stationary contacts are connected in series with the circuit to be switched while movable contacts are attached with a push button.
Momentary-contact switch, which include mainly pushbutton switches, are used when it is necessary to only briefly open or close a connection.
A normally closed pushbutton switch acts as a closed circuit (passes current) when left untouched.
SWITCH FOUND AT HOME
Switch at the refrigeratorFunction: It saves energy because it only opens when the fridge’s door is also opened.
Switch at the flashlightFunction: It only omit light when pressed.
Solid wire is thicker than stranded wire. It consists of only one thick strand‚ it is much more durable than the stranded wires.
It provides protection against corrosion.Ideally suited for outdoor applications.
Stranded wires are much more malleable than that of solid wire. The twisted structure of the strands allows bending. So‚ the stranded wires are well-suited for applications that require flexibility and movement.
FUNCTIONIt makes the wire flexible. It is suitable for devices that requires repetitive motion.
|SOLINOID WIREA wire for a solenoid that is used in a coil of enameled or insulated wire in a corkscrew shape wrapped around a rod-shaped armature usually made of iron.|
FUNCTIONIt is used to form a solenoid wire coil to create an electromechanical device capable of producing a magnetic field and motion of the armature.It has wide applications which include use in automobile starters, switches, valves and inductors in electronic circuits.
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.Resistors can also be used to provide a specific voltage for an active device such as a transistor.
An electrolytic capacitor has one of the biggest capacitances compared to other capacitors. It is used in electrical circuits with a low frequency and high current, such as the circuits of a power-supply filter which have fluctuating currents and output voltage. If there are no rechargeable batteries present, then an electrolytic capacitor can offer the same kind of low-frequency electric current capacity.
It neutralizes other capacitors.Mostly found working as filters in loud speakers. It aims to decrease the amplifier’s vibration.
|DIALECTRIC CAPACITORFUNCTIONTo prevent electrons from traversing between the plates within the capacitor. Electrons on one plate can only reach the other via a conductive path outside the capacitor.To separate the plates by as small a distance as possible, such that the electrons in one plate experience strong repulsion from electrons in the other.|
A transformer is a device that changes an electrical voltage or current from one level to another. (In radio frequency applications, it is used to couple the RF electronic circuits.)FUNCTIONConvert high voltage alternating current (AC) to desired low voltage alternating current (AC). Such transformers are called step down transformers.Convert low voltage alternating current (AC) to desired high voltage alternating current (AC). Such transformers are called step up transformers.Electrically separate one part of the circuit (or any other electrical system) from the other part, termed as ‘electrical isolation’. Such transformers are called isolation transformers.
|POWER CABLEFUNCTIONTo provide power from a power source to some piece of equipment or tool.|
The basic and sole purpose of a power cable is to transport electrical energy from the source of the electricity to the device.
|LAN CABLE FUNCTIONEthernet cables connect devices such as PCs, routers, and switches within a local area network.These physical cables are limited by length and durability. If a network cable is too long or of poor quality, it won’t carry a good network signal. These limits are one reason there are different types of Ethernet cables that are optimized to perform certain tasks in specific situations.|
Step voltages up or step voltages down, by transformer action, to the specified ac line voltage.Provide some method of voltage division to satisfy equipment needs.Change ac voltage to pulsating dc voltage by either half-wave or full-wave rectification.Filter pulsating dc voltage to a pure dc steady voltage for equipment use.Regulate power supply output in proportion to the applied load.
A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. They’re designed for long-distance, high-performance data networking, and telecommunications. Compared to wired cables, fiber optic cables provide higher bandwidth and transmit data over longer distances. Fiber optic cables support much of the world’s internet, cable television, and telephone systems.
FUNCTIONFiber optics support a higher capacity. The amount of network bandwidth a fiber cable can carry easily exceeds that of a copper cable with similar thickness. Fiber cables rated at 10 Gbps, 40 Gbps, and 100 Gbps are standard.Because light can travel for much longer distances over a fiber cable without losing its strength, the need for signal boosters is lessened.A fiber optic cable is less susceptible to interference. A copper network cable requires shielding to protect it from electromagnetic interference. While this shielding helps, it is not sufficient to prevent interference when many cables are strung together in proximity to one another. The physical properties of fiber optic cables avoid most of these problems.
|24 PIN POWER CONNECTORA 24-pin power supply is a type of computer power supply using a 24-pin primary connector. Older power supplies came equipped with only a 20-pin primary connector. The extra four pins provide additional power to the computer’s motherboard, which in turn provides power to internal components.|
FUNCTIONA power supply converts voltage from power lines into lower levels of voltage for use by a computer’s internal components. These internal components have different voltage requirements, and a power supply must be able to accommodate this. Several different connectors are used to supply all parts of the computer with power.
The Video Graphics Array (VGA) cable is typically used for displaying video from a computer to a video display such as an HDTV or monitor. VGA cables are capable of displaying RGB video onscreen at both low and high resolutions. But, because the VGA signal is analog, its resolution won’t be as high as DVI and HDMI cables are capable of. The VGA port is standard on most desktop computers from the 1990s through the 2010s, so it may be a good option to use if your display monitor has a VGA port and you can’t use DVI or HDMI.
|USB CABLEThe term USB stands for “Universal Serial Bus”. USB cable assemblies are some of the most popular cable types available, used mostly to connect computers to peripheral devices such as cameras, camcorders, printers, scanners, and more. |
FUNCTIONUSB cables are “Hot Pluggable”, in other words you can connect and disconnect the cables while the computer is running without fear of freezing the computerUSB cables are fast, transferring up to 480Mbps. Compare that to serial communication which transfers data at about 20KbpsUSB cables carry power as well as signals. This allows for “USB powered” gadgets as well as recharging batteries in cameras and other USB peripheralsUSB cables are designed with several distinct connector types, making it easy to identify which plug goes into the computer and which plug goes into the peripheral device
