Electromechanical switches are devices used to make, break, or change the route of electrical and electronic current flow in circuits. Switches represent a vital electronic component throughout many electronic circuits. Despite the rise in popularity of electronic or semiconductor based circuits for switching, electromechanical switches are still widely used. Though they provide many functions, their simplest is to interrupt a circuit so that it can be switched on and off. Other types of electromechanical switches enable circuits to be routed through to different points and, depending on the circuit design, switches can provide a broad range of switching functions.

Thyristors, also known as silicon controlled rectifiers (SCR), are semiconductor devices that can act as electronic switches to control circuits with high voltage and current levels. Though thyristors are relatively uncommon components, they are highly useful in controlling power circuits. As such, they are ideal for many power control applications, especially in those where current and voltage levels are elevated. Despite this, thyristors can also be useful in low power applications such as light control, power supply protection, and others. Thyristors are simple parts and relatively inexpensive, making them a helpful solution for many circuits.

Electrical resistors are a common electrical component that provide a circuit with electrical resistance. This may be in place to reduce current flow, divide voltages, adjust signal levels, terminate transmission lines, and cater to other operations. Resistors are basic components of electronic circuits, and they may be found in a multitude of electronic devices and networks. Varistors are a special type of resistor, allowing for varying resistance to serve as protective devices against excessive transient voltages. Varistors play important roles in a variety of applications to protect equipment and lines, and they have been prevalent in electronics since the early 1900’s. In this blog, we will provide a short overview on the functionality of varistors, as well as the applications that they benefit.

Memory cards are a type of non-volatile data storage device that often utilize flash memory to store data. There are multiple types of memory cards, though one of the most common is the Secure Digital (SD) card. SD cards are designed for the use of storing data for portable devices, and their standards were set forth by the joint efforts of SanDisk, Panasonic, and Toshiba after their initial release in 1999. The standard that was established quickly was adopted by many other electronic manufacturers in the industry, and SD cards became commonplace for digital cameras, mobile phones, personal computers, and beyond.

When buying RAM for the first time, whether to upgrade or build a new computer, choosing the right configuration can be a daunting task. There are a variety of terms for different performance specifications, and often the most expensive, top of the line models are well beyond what may be needed to improve your computer’s performance. RAM, or Random Access Memory, is hardware that holds the temporary data that your computer is using at a given moment, including programs and the OS. In this blog, we will discuss some of the basics of RAM, as well as how to choose the correct configuration for your system.

Resistors serve importance within electrical systems through the reduction of current flow, dividing voltages, and adjustment of signal levels to aid in electrical resistance. Carbon composition resistors are a type of fixed resistor that was developed in the early 20th century. They have become more outdated in more recent years, preceded by newer fixed resistors, though still have some important utilization in various applications. In this blog, we will provide an overview of what carbon composition resistors are, their advantages and disadvantages, as well as their modern applications.

Resistors are an important component to help reduce current and restrict electrical current flow. Wire wound resistors, in particular, are important in applications where there are large amounts of power that need dissipation. They are one of the first types of resistors to be utilized, and their functions and structure have changed little over the years. Wire wound resistors have been superseded by other resistors, but their qualities and functionality in applications where other resistors fail make them still very reliable and widely used.

In electrical engineering, a switch is used to interrupt current or divert it from one conductor to another. When an electrical contact is open, it means that the switch is off and not conducting because the contacts are separated; when an electrical contact is closed, it means that the switch is on and conducting because the contacts are touching.

Metal film resistors are one of the most common types of axial resistors. They use a thin metal layer as a resistive element on an otherwise non-conducting body. The first metal film resistor was manufactured in the 1930s by Dubilier.
