A metal clad switch refers to a type of switch that is housed in a protective metal enclosure. This enclosure is typically made of steel or aluminium and is designed to provide additional protection to the switch against environmental hazards such as dust, moisture, and mechanical damage.

Metal clad switches are often used in industrial settings where there is a higher risk of electrical accidents and equipment damage. The metal enclosure helps to prevent accidental contact with the live parts of the switch and serves as a shield against electromagnetic interference (EMI) and radio frequency interference (RFI).

Metal clad switches are often designed to be modular and can be easily assembled and disassembled. They also typically have high breaking capacities, meaning they can safely interrupt high levels of electrical current in the event of a fault or overload.

Metal clad switches are a reliable and durable option for controlling electrical power in industrial environments where safety and reliability are essential.
