Disconnect Switch

A disconnect switch, also known as an isolator switch, is an electrical device used to interrupt or isolate the flow of electric current in a circuit. It is primarily used for safety purposes, allowing the power supply to be swiftly shut off during maintenance or emergency situations.

Disconnect switches are commonly found in electrical systems that require manual control over power shutdowns, such as industrial machinery, electrical panels, and power distribution systems. They can be found in both residential and commercial settings.

The main function of a disconnect switch is to physically separate the circuit from the power source, ensuring that no electricity can flow through the circuit. This aids in preventing electrocution and protecting workers from potential hazards when working on electrical equipment.

Disconnect switches are typically equipped with visible "ON" and "OFF" positions to indicate whether the circuit is active or not. They come in various sizes and configurations, ranging from simple toggle switches to more complex rotary or knife-style switches.

It's important to note that disconnect switches should only be operated by qualified personnel who are knowledgeable about electrical safety procedures. Improper usage or lack of understanding can lead to serious accidents or damage to equipment.
