The primary purpose of an isolator switch is to provide an extra layer of protection by disconnecting electrical devices or circuits from the power source. This disconnection is crucial during maintenance, inspection, or repair work, as it minimizes the risk of electric shocks or short circuits, ensuring the safety of personnel and equipment.

Our isolating switch is specially designed for disconnecting the AC and DC sides of the solar system. Due to its excellent quality performance, we have reached cooperation with many big brands. Combined with other accessories, our switches can provide effective protection against any kind of overvoltage or overload problem.

Due to our stringent quality process, we ensure that our disconnectors are inspected and tested at every production step. IP66 shells and MC4 connectors are available for your own selection. Contact us now to enjoy super-value discounts, move forward with us, and represent our products!




Our team has continuously improved the structure and production process of the isolating switch and has obtained many patents for this. Our isolating switch has its own patents and special instructions, making it safer, faster, and more stable to use. With our isolating switches, arc interruption within 3 milliseconds can be achieved, quickly cutting off the circuit and protecting the system’s safety.


MOREDAY has realized the automatic production of 70% of the isolation switch process, ensuring that the yield rate of the isolation switch produced is above 99.8%. Our strong delivery capacity has made us a supplier to many international brands.

Frequently Asked Questions

You'll find answers about our products. If your question is not answered below,
please feel free to contact us.

A: The primary purpose of an isolator switch is to disconnect a specific circuit or device from the main power source, ensuring the safety of personnel and equipment during maintenance, inspection, or repair work.

A: No, isolator switches and circuit breakers are not the same. Circuit breakers are automatic isolator switches that provide overcurrent protection, while isolator switches disconnect electrical devices or circuits from the power source for safety purposes.

A: The frequency of inspection and maintenance depends on the specific switch and its operating environment. However, as a general rule, it is recommended to inspect and maintain your isolator switch at least once a year or more frequently if the switch is exposed to harsh environmental conditions.

A: It is strongly advised against installing an isolator switch by yourself unless you are a qualified and licensed electrician. Incorrect installation can lead to accidents, malfunctions, and damage to your electrical system. Always hire a professional to ensure the proper and safe installation of your isolator switch.

A: Isolator switches can have a long service life if they are well maintained and used correctly. However, over time, wear and tear may occur, and the switch may need to be replaced. Regular inspection and maintenance can help identify issues early and allow you to replace the switch before it fails or causes damage to your electrical system.

A: Isolator switches are commonly used in various applications, including electrical power systems, industrial equipment, and residential settings. They help to ensure the safety of personnel and equipment by disconnecting specific circuits or devices from the main power source during maintenance, inspection, or repair work.

A: Isolator switches, by themselves, do not provide protection against electrical faults such as overcurrent or short circuits. However, they can be used in conjunction with other protective devices, such as circuit breakers or fuses, to provide a comprehensive protection solution for your electrical system.

A: When selecting an isolator switch, consider factors such as voltage rating, current rating, type of load, environmental conditions, and safety features. These factors will help you choose a switch that is compatible with your specific application and provides the necessary protection and performance.

A: To ensure the safe operation of an isolator switch, always follow the manufacturer’s guidelines and adhere to relevant codes and regulations. Some general safety precautions include:

Turn off the power source before operating the isolator switch.
Use appropriate personal protective equipment (PPE) when working with electrical systems.
Ensure the isolator switch remains in the off position during maintenance or repair work by using built-in safety features such as interlocks and padlock provisions.

A: Some isolator switches, particularly electrical isolators, can be operated remotely using control systems. This allows for increased safety and convenience, as operators can disconnect specific circuits or devices from the main power source without physically interacting with the switch.
