This text describes several different types of switches and some of their characteristics and applications, and also touches on the characteristics of other electrical components and technologies associated with switches. The following is a detailed explanation of the points mentioned in the text:
Classification of switches:
Knob type: operated by rotation and can usually be locked in a specific position.
Plate-action: including button switches and boat switches, also operated by moving or toggling, and can likewise be locked into a state.
Push-button type: usually operated by pressing and releasing, most do not have a locking function and return to their original state after release.
Self-locking feature of the switch:
Knob and plate-action switches can often remain in the on or off state after operation, which is known as self-locking.
Pushbutton switches do not usually have a self-locking feature, but they can be combined with components such as relays to realize specific circuit functions.
Applications and Characteristics of Micro Switches:
Micro switches are typically used where precise control or fast response is required.
They protect equipment by automatically disconnecting the power supply when the load current exceeds a certain value (e.g. 10A), preventing overloading.
Characteristics of electrical components and technology:
Enclosure rating: The enclosure has a high level of protection against a certain level of dust and water intrusion, which helps ensure the safe operation of the switch and internal components.
Docking Capability: The switch can be docked into raceways and conduits, which facilitates installation and wiring.
Capacity and Number of Functional Component Positions: The switch has a small capacity, which means it can be fitted with fewer functional component positions for specific or simple applications.
Lightning protection components: Adopting the full protection mode of common mode and differential mode, which is carefully developed through new technologies and processes, it can effectively prevent lightning damage to electrical equipment.
Through-current capability and response time: High through-current capability and fast response time, which ensures efficient and stable operation of the switch in the circuit.
Residual Voltage: Low residual voltage, which helps to reduce the voltage fluctuation generated when the switch is disconnected from the circuit and protects the stability of the circuit and equipment.
Temperature-controlled disconnect technology and overcurrent protection technology: These technologies protect circuits and equipment from damage caused by overheating and overcurrent, improving the safety and reliability of the system.
Working status indication: the working status of the switch is displayed through indicator lights or other means, which is convenient for users to understand the status of the circuit.
In summary, this text focuses on the characteristics of different types of switches, their applications and the properties of the electrical components and technologies associated with them. These characteristics and technologies ensure the safe, efficient and stable operation of switches in circuits and meet the needs of different application scenarios.
