While wireless internet and network connectivity has become widespread and commonly used by many, ethernet switches still remain an integral part of most data networks. As the most common form of network switch, ethernet switches may range in size with small to large variations being available, and they are also found in industrial control settings where they can excel with their robust performance qualities. In this blog, we will go over ethernet switches and how they assist the various networking devices and electronic hardware that they are implemented in.

Switches are extremely commonplace electronic devices, allowing for control to be assumed over a system in order to actuate various processes, switch between power modes, and much more. The rocker switch in particular is a very popular form of switch featuring a mechanism that may rock between two or more positions when actuated. Also known as see-saw switches, rocker switches will often have a side raise when another is depressed, allowing it to visually and mechanically alter between two states with a central pivot point. Depending on one’s particular needs and the application in question, there are a number of rocker switch types that may be used.

Many aircraft are equipped with either a 14- or 28-volt direct current electrical system. Some systems are more advanced than others, but the basic aircraft electrical system comprises the following components: alternator/generator, battery, master/battery switch, alternator/generator switch, bus bar, fuses, & circuit breakers, voltage regulator, ammeter/load meter, and the associated electrical wiring. In this blog, we will discuss the main parts of aircraft electrical systems.

The aircraft hydraulic system is an extremely important element of numerous aircraft, allowing for high amounts of energy to be transferred for the actuation of systems and flight surfaces. As a system that relies upon contained liquids under pressure, hydraulics may be used for opening cargo doors, deploying landing gear, actuating aircraft rudders and spoilers, operating windshield wipers, and much more. As hydraulic systems help both small and large tasks be carried out, their proper functionality is paramount. While a number of factors can affect the functionality of hydraulic systems, the most important are temperature and pressure.

Networks are critical for supporting business, fostering communication, providing entertainment, and beyond. A key component of every network is the network switch, which allows devices within the network to connect to transmit data and share resources. The network switch operates at the Data Link layer of the OSI model (layer 2). It receives packets being sent by devices connected to its physical ports and redistributes them through the ports that lead to the device to which the packet is intended to go. They are also able to work at the network layer, layer 3, where routing occurs. While switches are used in networks based on ethernet, Fibre Channel, ATM (Asynchronous Transfer Mode), and InfiniBand, the majority of switches use ethernet.

For a computer system to efficiently carry out its standard operations and execute various programs, it requires memory for data handling. On standard motherboards, a device known as a memory socket, memory slot, or RAM slot is provided for the insertion of computer memory. Depending on the configuration of the motherboard, there may be two to four memory slots, and the slot types present will dictate what type of RAM may be inserted. In this blog, we will discuss memory sockets and RAM more in detail, allowing you to know how to procure compatible computer hardware for your computer system.

Whether they are electromechanical or solid state, relays, solenoids, and contactors are all examples of switches. However, they all have differences and unique characteristics that make them better suited to different applications. This blog will cover all three and discuss certain considerations to make when deciding which device is best for you.

When watching a propeller aircraft begin to operate as the engine is turned on, it can be astounding to witness just how fast propellers can spin. Due to the speed at which propellers are operated at for achieving sufficient thrust, it can be difficult to see which way they are revolving. Furthermore, one may wonder if there is a standard for direction, and whether all move the same way. While a grand number of propellers tend to spin in a clockwise direction, there are some outliers that present the opposite operation.

Flight control surfaces are common aircraft devices that allow for pilots to manipulate the flight dynamics of the vehicle. Coming in the form of aviation parts such as ailerons, elevators, rudders, spoilers, and flaps, flight control surfaces are paramount for the efficiency and optimization of piloting and flight. As aircraft often operate in environments where they may face strong winds, prop washer, or jet efflux hazards, various means of protection are implemented in order to ensure the safety of such components.

On any fighter type jet, a circuit breaker panel is found on the underbelly or side of the cockpit, right below where the pilot would sit. Much like a circuit breaker you would find at home, the aircraft circuit breaker would be like a box or panel that acts like a protective device for opening a circuit automatically when excessive current is flowing through it. A circuit breaker may be reset to restore the circuit after a fault causing excessive current has been corrected. Essentially the circuit breaker panel is an electrical protecting safety device which is why most homes, helicopters, airplanes, and other facilities must have a circuit breaker.
