1, knife switch: used to switch the circuit on and off,It is a manually operated switchgear. Combined switch: integrates a variety of switch functions in one, can achieve multiple control of the circuit. Fuse: When the current in the circuit exceeds the rated value, the melt in the fuse will be fused due to the thermal effect, thus cutting off the circuit and playing a protective role.
2, electronic components include: resistors, capacitors, inductors, crystal diodes, connectors, potentiometers, etc. Resistance Resistance is represented in a circuit by R plus a number, for example, R1 indicates a resistor numbered 1. The main functions of the resistance in the circuit are: shunt, current limiting, voltage partial, bias, etc. Capacitor A capacitor is in a circuitIt is usually represented by C plus a number (such as C13 for a capacitor numbered 13).
3, resistor. A capacitor. The inductor. The transformer. A semiconductor. Thyristors and field effect tubes. Electron tube and camera tube. Piezoelectric devices and Hall devices. Photoelectric devices and electroacoustic devices. Surface assembled devices. 1 Integrated circuit device. 1 Electronic display device. 1 Switch and connector. 1 Relay, photoelectric coupler device.
K: relay; X: crystal oscillator, ceramic resonator.
R (Resistance) resistor, VR adjustable resistor, RK row resistor, RV varistor, C (Capacitance) capacitor, crystal oscillator X, L inductor, B (Bridge) rectifier bridge, D (Diode) diode, DW regulator diode, LED indicator or digital tube, JK relay, IC Integration or chip or MCU, TWRegulator block, Q triode, CN socket, T transformer, SW or K switch.
For example, R indicates a resistor and W indicates a potentiometer. The second part: the material, represented by letters, indicates what material the resistor is composed of, T-carbon film, H-synthetic carbon film, S-organic solid, N-inorganic solid, J-metal film, Y-nitridation film, C-deposition film, I-glass glaze film, X-wire wound. The third part: classification, generally represented by numbers, individual types are represented by letters, indicating what type the product belongs to.
There are many symbols in the circuit board, they all represent: resistance is used in the circuit"R" plus a number. Capacitance in the circuit is generally represented by "C" plus a number. Crystal diodes are commonly represented in circuits with a "D" plus a number.
K: switching tube X: low-frequency low-power tube G: high-frequency low-power tube D: low-frequency high-power tube A: high-frequency high-power tube. In addition, the 3DJ type is a field effect tube, and the BT head indicates a special semiconductor component. The most basic function of the transistor is amplification, which can turn the weak electrical signal into a signal of a certain strength, of course, this conversion still follows the conservation of energy, it is only the energy of the power supply into the energy of the signal.
