Fischer Elektronik electrical components are devices for transmitting electrical energy or signals, typically composed of several wires or groups of wires. They consist of one or more mutually insulated conductors with an outer insulating protective layer, serving as wires that transmit power or information from one location to another. Typically, they are rope-like cables formed by twisting several wires or groups of wires (each group having at least two), where each group is mutually insulated and often twisted around a central core, with the entire assembly covered by a highly insulating sheath. Cables feature internal conductivity and external insulation.

Fischer Elektronik electrical component principles

Inductance refers to the alternating magnetic flux generated inside and around a conductor when alternating current flows through it; it is the ratio of the magnetic flux in the conductor to the current producing this flux. When direct current flows through an inductor, only static magnetic field lines appear around it, unchanged over time; however, when alternating current flows through a coil, the surrounding magnetic field lines change with time. Analyzed according to Faraday's law of electromagnetic induction (magnetism generating electricity), changing magnetic field lines induce an electromotive force (EMF) at both ends of the coil, which acts as a "new power source." When a closed loop is formed, this induced EMF generates an induced current. According to Lenz's law, the total magnetic flux generated by the induced current attempts to oppose the change in the original magnetic flux. Since the change in the original magnetic flux stems from changes in the externally applied alternating power source, the inductive coil objectively exhibits the characteristic of opposing changes in current in an AC circuit. Inductive coils have characteristics similar to inertia in mechanics, termed "self-induction" in electrical engineering. Sparks often occur at the instant of opening or closing a knife switch, caused by the high induced EMF resulting from self-induction.

Fischer Elektronik electrical component structure

The simplest switch consists of two metal pieces called "contacts." When the two contacts touch, they form a closed circuit for current flow; when they do not touch, the circuit is open. When selecting contact metals, their corrosion resistance must be considered, as most metals form insulating oxides after oxidation, preventing normal contact operation. Factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity must also be considered when selecting contact metals. Corrosion-resistant metals are sometimes plated onto the contacts, generally on the contact surfaces, to avoid performance degradation due to oxides. Sometimes non-metallic conductive materials, such as conductive plastics, are used for the contact surfaces. In addition to contacts, switches contain movable parts that make or break the contact connection. Depending on the type of movable part, switches can be classified as lever switches, push-button switches, rocker switches, etc., and the movable part can also be other types of mechanical linkages.

Fischer Elektronik electrical component composition

The printed circuit board mainly consists of pads, vias, mounting holes, traces, components, connectors, copper pours, and electrical boundaries. ① Pad: A metal hole used for soldering component pins. ② Via: Includes metallic vias and non-metallic vias; metallic vias are used to connect component pins between layers. ③ Mounting hole: Used to secure the printed circuit board. ④ Trace: Copper film forming an electrical network to connect component pins. ⑤ Connector: A component used for connections between printed circuit boards. ⑥ Copper pour: Copper filling for the ground network, which can effectively reduce impedance. ⑦ Electrical boundary: Defines the dimensions of the printed circuit board; no components on the board may extend beyond this boundary.
