Detailed Breakdown of the Description

1. Electrical Wall Switch Socket PVC Mounting Block

• Function: This is the core purpose. It's a frame that you screw onto a standard electrical back box (the metal or Plastic Box inside the wall). It provides a perfectly flat and flush surface to attach the final switch or socket faceplate.

• Use Case: Essential for tiled walls, brick cladding, or any situation where the wall finish is thicker than the standard depth the electrical box is set for. It "bridges the gap" between the box and the wall surface.

2. Application: Electric Wires Installation

• This is a broad category. More precisely, its application is in finalizing the electrical wiring installation for switches and sockets, ensuring a safe, professional, and code-compliant finish.

3. Material: uPVC (Unplasticized Polyvinyl Chloride)

• Properties: uPVC is a rigid, durable, and non-conductive plastic. It's resistant to impact, moisture, and corrosion, making it an excellent and safe choice for electrical applications.

• Why it matters: Being plastic, it will not rust (unlike metal) and is a good insulator, adding a layer of safety.

4. Color: White / Custom

• White: This is the standard, most common color to match typical white switch plates and modern interiors.

• Custom: The manufacturer can produce these in other colors if a large enough order is placed (e.g., to match specific architectural requirements or other switchgear colors like black or grey).

5. Size: 120*75*38mm / Custom

• 120mm (Height) x 75mm (Width): This is a common "2-gang" size, meaning it is designed to hold two switches or two sockets side-by-side in a single unit.

• 38mm (Depth): This is the depth of the block itself, which extends the electrical box out from the wall.

• Custom: ZIBO HUIWEN can also produce blocks in different sizes (e.g., for a single switch/socket or three-gang units) for large orders.
