The deep MK switch box is one of the essential components in building electrical wiring systems, used for installing and protecting electrical switches and sockets, especially smart models. These boxes are manufactured from galvanized steel sheet to have high resistance to moisture, pressure, and heat. The term “deep” refers to the greater depth of the internal compartment of the box, which provides sufficient space for the passage of wires and electrical modules.
In fact, with its standard design, the deep MK switch box protects the internal connections of the switch and socket against impact, rust, and short circuits and significantly increases the safety of the electrical network. For this reason, this type of box is widely used in smart wiring projects, residential buildings, and industrial environments.
The deep MK switch box, due to its engineered design and the use of galvanized steel sheets, has numerous advantages over standard models. The most important of these advantages are:
High resistance to impact and pressure: Due to the use of hot-dip galvanized metal, these boxes have very high strength and are not damaged by mechanical pressure, impact, and temperature changes.
Complete protection of wiring and smart switches: The greater height of the box provides sufficient space for the passage of wires and smart modules and minimizes the risk of short circuits or damage to the wires.
Prevention of rust and corrosion: The hot-dip galvanized coating on the box body prevents oxidation and rust in humid environments and increases the product’s durability.
Easy and precise installation in construction projects: The standard design of the MK switch box allows it to be easily installed inside the wall and leaves sufficient space for installing the switch and socket.
Higher safety in the electrical wiring system: Using a metal box reduces the probability of fire caused by wire overheating and increases the project’s safety level.
Usable in industrial and domestic projects: Due to the variety in dimensions (50, 70 millimeters), these boxes can be used both in construction projects and in industries.
Long service life and reduced maintenance costs: High resistance to wear and moisture eliminates the need for repair or replacement of the box in the long term and reduces costs.
As mentioned, the deep MK switch box is manufactured from metal sheets. However, the main question is: exactly what type of metal and alloy are these sheets made of, and do they have good resistance in high-stress environments? Regarding the types of manufacturing materials for the deep MK switch box, we must point out that, given the high importance of maintaining safety in cabling networks, the most resistant available alloys are often used in manufacturing its body.
Currently, steel alloys are one such type of material. If you have noticed, in the catalog of these products, the material type is stated as factory-galvanized. Generally, steel materials undergo the galvanization process, so metals such as aluminum are not usually mentioned under this title. Therefore, the manufacturing material type of the MK switch box is galvanized steel alloys. Many advantages can be listed for the galvanization coatings on this product, which we will discuss in the next section.

Since the deep MK switch box is made from galvanized steel sheet, if you have paid attention to the body of these boxes, they have a shiny surface with a relatively silver color. This is related to the type of coating applied to these switch boxes — a protective coating usually referred to as hot-dip galvanizing.
In general, two types of processes, hot-dip galvanizing and cold galvanizing, are used for strengthening metals, with the cold galvanized type having less resistance compared to hot-dip galvanized. Given the high importance of cabling networks and maintaining the resistance of the part, manufacturing companies always strive, regardless of the initial production cost, to prioritize the use of the hot-dip galvanization process.
Therefore, this exact type of coating is also used for manufacturing the deep MK switch box. The advantages that can be listed for it include rust prevention, prevention of discoloration, oxidation, and corrosion, as well as preventing the structural deterioration of the part in humid environments. By obtaining galvanized parts, the costs of repair, maintenance, or their replacement will be completely eliminated in the long term.
Compared to other models, this switch box has high strength and protects the switch against external damage, pressure, impact, and moisture.
In general, electrical switches are highly delicate and sensitive, and the tools used in them are prone to damage. Using a metal electrical box will increase the service life and safe operation of the switches. It will also significantly reduce your need for early replacement and the payment of additional costs for switch repair.
For protecting smart switches as well, the use of the deep MK switch box is very common. For example, for BMS smart switches, the 70×70 type with a height of 50 millimeters and thickness of 60 millimeters is used.
Compliance with global standards in the manufacture of this box has led employers to use it for various purposes, including residential and industrial electrical wiring systems.
Given that this box can be used in numerous cases, it will have the ability to be installed in flush-mounted and surface-mounted forms depending on the situation. Of course, in most cases, this box is installed in a flush-mounted manner, but if necessary, it will also be possible to install it in a surface-mounted manner. In general, the MK switch and socket box is considered one of the widely used and efficient equipment in building electrical wiring. First, this box is placed inside the wall, and then, with complete precision, the wire strands and its related accessories are placed inside this metal enclosure.
In general, this switch and socket box is made from metals such as galvanized, cast iron, and aluminum; for this reason, it has high resistance to destructive effects and is usable for a long time. Of course, it is necessary to consider that the quality of the material used in manufacturing these products has a direct relationship with their level of resistance and service life. Since the application and place of use of the metal electrical box varies, this product is manufactured in different dimensions, sizes, and designs.

Given that the deep MK switch box is manufactured from metal and galvanized sheets, it has better resistance and quality compared to plastic and fireproof models, hence it is offered at a higher price than these models. Nevertheless, among the various manufacturers engaged in making and supplying this product, Rafi Industrial Group sells the metal electrical box with excellent quality and a reasonable price. In fact, by eliminating intermediaries and directly supplying its products, this group has significantly reduced the final price for customers.

The question is always raised by buyers as to what types of sizings exist for the deep MK switch box. Before introducing the relevant sizes, starting with the introduction of the dimensions 70x70x35 millimeters, we must state that this model, given its depth and height of 35 millimeters, is usually considered among the low-height switch boxes, so the feature of being deep cannot be attributed to this model.
However, other sizes of this product, such as 70x70x50 and also 70x70x70, are considered deep MK switch boxes. These switch boxes have a depth of 50 millimeters and also 70 millimeters, so they have sufficient volume and depth to support and hold numerous electrical cable connections.
Given the type of application these switch boxes have, a controlled thickness is usually considered for their design and manufacture. The most common dimensions related to the thickness of these parts mostly include 0.6 and 0.8 millimeters. Of course, other dimensions such as 0.7, 0.9, and 1 millimeter are also manufactured for these parts, which certainly increases their physical resistance. In many industrial projects, the use of deep models with high thickness is among the most common of these parts requested by electrical cabling network contractors.

To meet the volume of customer needs, the packaging type for switch boxes is usually in cartons of several pieces. The number of deep MK switch boxes in each package can typically be 70 pieces. Of course, their smaller sizes are often packaged in quantities of 100 pieces as well. With this high quantity, you can easily carry out the transportation and transfer of the parts to the project site. Furthermore, for extensive areas such as industrial and commercial projects, this quantity will be completely sufficient.
