Trafomic electrical components are a new type of contactless switching device composed entirely of solid-state electronic components. It utilizes the switching characteristics of electronic components (such as switching transistors, triacs, and other semiconductor devices) to achieve contactless, spark-free circuit connection and disconnection, hence it is also called a "contactless switch". A solid-state relay is a four-terminal active device, where two terminals are input control terminals and the other two are output controlled terminals. It has both amplification drive function and isolation function, making it very suitable for driving high-power switching actuators. Compared to electromagnetic relays, it offers higher reliability, is contactless, has a long service life, fast speed, and low external interference, and has been widely used [1].

Trafomic electrical components function

Low-power resistors are typically carbon film types encapsulated in plastic housings, while high-power resistors are usually wirewound resistors, made by winding high-resistivity metal wire around a ceramic core. If a resistor's resistance value is close to zero ohms (for example, a large cross-section wire between two points), the resistor offers no obstruction to current, and the circuit parallel to this resistor is short-circuited, resulting in infinite current. If a resistor has infinite or very high resistance, the circuit series-connected with this resistor can be regarded as an open circuit, with zero current. Resistors commonly used in industry fall between these two extremes; they have a certain resistance and allow a certain amount of current to pass, but the current is not as large as in a short circuit. The current-limiting function of a resistor is similar to the effect of a small-diameter pipe connected between two large-diameter pipes restricting water flow. Resistance, usually abbreviated as R, is a fundamental property of a conductor, related to the conductor's size, material, and temperature. Ohm's law states that I=U/R, so R=U/I. The basic unit of resistance is the ohm, represented by the Greek letter "Ω". It is defined as the resistance value corresponding to one ampere of current generated when one volt of voltage is applied across a conductor. The main function of a resistor is to impede the flow of current. In fact, "resistance" refers to a property, while "resistor" in electronic products usually refers to the component itself. Ohm is often abbreviated as Oh. Common units for expressing resistance values also include kilo-ohm (kΩ), mega-ohm (MΩ), and milli-ohm (m Ω).

Inductors are generally composed of a bobbin, winding, shield, encapsulation material, magnetic core, or iron core. 1, Bobbin: The bobbin refers to the support for winding the coil. Most larger fixed inductors or adjustable inductors (such as oscillator coils, choke coils, etc.) involve winding enameled wire (or silk-covered wire) around the bobbin, then inserting a magnetic core, copper core, or iron core into the inner cavity of the bobbin to increase inductance. Bobbins are usually made of plastic, bakelite, or ceramic, and can be shaped differently according to actual needs. Small inductors (such as color-coded inductors) generally do not use bobbins but wind enameled wire directly onto the magnetic core. Air-core inductors (also known as formless coils or air coils, mostly used in high-frequency circuits) do not use magnetic cores, bobbins, or shields; instead, they are wound on a mold which is then removed, leaving a certain distance between the coil turns. 2, Winding: The winding refers to a set of coils with specified functions and is the basic component of an inductor. Windings are divided into single-layer and multi-layer types. Single-layer windings come in two forms: close-wound (wires are wound circle by circle) and spaced-wound (a certain distance is kept between each turn); multi-layer windings include layered flat winding, random winding, honeycomb winding, and others. 3, Magnetic Core and Magnetic Rod: Magnetic cores and rods are generally made of materials such as nickel-zinc ferrite or manganese-zinc ferrite. They come in various shapes such as "I" shape, cylindrical, cap shape, "E" shape, and pot shape. 4, Iron Core: Iron core materials mainly include silicon steel sheets and permalloy, and their shape is mostly "E" type. 5, Shield: To prevent the magnetic field generated by some inductors during operation from affecting other circuits and components, a metal shield is added (such as oscillator coils in semiconductor radios). Using a shield increases coil loss and reduces the Q value. 6, Encapsulation Material: Some inductors (such as color-coded inductors, color-ring inductors, etc.) are sealed with encapsulation material after winding. Encapsulation materials include plastic or epoxy resin.

The simplest switch consists of two metal pieces called "contacts". When the two contacts touch, current forms a loop; when they do not touch, the current path is open. When selecting contact metal, its corrosion resistance must be considered, because most metals form insulating oxides after oxidation, preventing the contacts from working properly. Factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity must also be considered when selecting contact metal. Sometimes anti-corrosion metal is plated on the contacts. Plating is generally applied to the contact surface to avoid performance degradation due to oxides. Sometimes non-metallic conductive materials, such as conductive plastics, are used for the contact surface. In addition to contacts, switches have movable parts that make the contacts conductive or non-conductive. Switches can be classified into toggle switches, push-button switches, rocker switches, etc., based on the different movable parts, and the movable parts can also be other types of mechanical linkages.
