Uses of a  knife switch

Educational Demonstrations:

Knife switches are often used in educational settings to demonstrate basic principles of electricity and circuits. They provide a tangible way for students to see how opening and closing a circuit affects the flow of electricity.

Historical Displays:

Due to their historical significance in early electrical systems, knife switches are sometimes used in museum exhibits or historical reenactments to illustrate the development of electrical technology.

Low Voltage Applications:

While they are less common in modern electrical systems, knife switches may still be used in low voltage or low current applications where a simple and reliable switch is needed, such as in hobbyist projects or certain industrial settings.

Emergency Shutdowns:

In some industrial settings, knife switches may be used as emergency shutdown switches for quickly disconnecting power in case of an emergency or equipment malfunction.

Backup Systems:

In certain situations where redundancy is important, knife switches may be used as backup switches alongside more modern switches or electronic controls to ensure that critical systems can still be operated manually in the event of a failure.
