The symbol for a thermal fuse used in any electrical circuit diagram. Symbols; Motor: Electric motor: Transformer: Change AC voltage from high to low or … Its essential component is a metal wire or strip that melts when too much current flows, which interrupts the circuit in which it is connected. The following symbols show the different components that can be found in an electrical circuit. Standard Circuit Symbols For Circuit Schematic Diagrams Circuit symbols are used in circuit schematic diagrams which show how a circuit is connected together electrically. Earth Circuit Symbol: Used in electronic circuits to represent the 0 volts of the power supply.

Misc. A resistor restricts or limits the flow of electrical current. A thermal fuse is a temperature sensitive switch. Fuses are devices containing a small piece of … Crystal Oscillator Used to generate clock signal of very precise frequency. It can also be defined as the real earth , when it is applied in radio circuits and power circuits. Thermocouple Short circuit, overloading, mismatched loads or device failure are the prime reasons for excessive current. Fuses and Electrical Protection Symbols. The standard circuit component symbols and circuit symbols are important for circuit schematic diagrams. ADC Analog to Digital converter is used convert analog signals (usually voltage) to digital values. Fuse Symbol represents the fuse that protects the circuit from over current. It operates on the temperature rather than the current unless the current is sufficient to increase the temperature above the threshold point. DAC Digital to Analog converter is used to convert digital code to analog signals.
