What Is a Switch Box?
A switch box is a component designed to house electrical connections and devices like switches and outlets. It facilitates the organization and protection of wiring systems and can be mounted in various ways, including embedded within or exposed on a wall.
Uses of Switch Boxes
Switch boxes are versatile, serving to install electrical fixtures securely. They accommodate the connections for switches and outlets, allowing for organized and safe electrical setups. The choice of switch box depends on the installation environment, such as wooden or concrete structures, and can support multiple devices in a single location.
Principle of Switch Boxes
The design and installation of switch boxes vary based on the building material and whether they are placed inside or outside, embedded or exposed. Options include easily mountable boxes for wooden structures and sealed steel plate boxes for concrete installations to prevent penetration by concrete. Exposed boxes, typically metal, are used where the box remains visible and may require environmental resistance.
Types of Switch Boxes
1. Embedded Type
Designed for integration into walls, these boxes are suited for various construction materials and come in multiple depths to accommodate different installation needs. Material options include steel plate and resin, with finishes like electrogalvanization or electrodeposition coating.
2. Exposed Type
Used mainly for retrofitting, exposed switch boxes are made from materials such as steel, cast iron, and resin. They feature conduit connection ports for wire insertion and are available in various dimensions to support multiple switches.
3. Special Type
Specialized for particular applications, these include mobile switch boxes for close machine operation, operating switch boxes for machine control in a handheld format, and distribution switch boxes for power supply and alarm signaling to devices. They are constructed from materials like polycarbonate resin and steel, offering features like flame resistance and waterproofing.
