The current limiting switch is one of the important components of the protection circuit and equipment

The current limiting switch is a common electronic device, which can protect the circuit and the electronic devices connected to the circuit by controlling the current in the circuit.Current limiting switchIt can play a protective role in the circuit to prevent equipment damage, short circuit, fire and other risks caused by abnormal conditions such as overcurrent, overload and short circuit.

The basic principle of current limiting switch is to use the principle of magnetic field induction to place an inductor coil in the circuit. When the current passes through the coil, the magnetic field is generated. The current limiting switch can control the current in the circuit by changing the impedance of the coil. When the current exceeds the set value, the current limiting switch will automatically cut off the circuit, thus protecting the circuit and equipment.

Current limiting switch is widely used in all kinds of electronic products and circuits, such as computers, mobile phones, TV, audio, etc., can effectively control the current, protect electronic products and equipment from current, overload and other abnormal conditions, to avoid equipment damage and safety risks.

However, the current limiting switch also has some disadvantages and limitations to be aware of. First of all, the current limiting switch cannot withstand high voltage and high current load, so before use, it is necessary to strictly follow the product specifications and parameters to avoid equipment damage due to the current limiting switch cannot withstand the load. Secondly, the current limiting switch controls the current in the circuit, which may affect the performance of the circuit to some extent. Therefore, reasonable circuit design and selection should be carried out.

In short, the current limiting switch is an important electronic device, can effectively protect the circuit and equipment, in the use of electronic equipment should also pay attention to the role of this device, to ensure the safety and stability of the equipment.
