Many will agree that locking mechanisms should be provided not only for entrance doors, but also for their interior counterparts. If for the former it is necessary to focus on the security of the mechanism, then for the latter, simplicity and ease of use, as well as small dimensions, will be more important. All these requirements are fully met, the locks are magnetic, which is why they are installed on the doors between rooms. At the same time, it should be noted that the service life of interior doors will be affected not only by the leaf itself and the door frame, which must be made of reliable materials, but also by locks, which must be not only of high quality, but also properly mounted.
IMPORTANT! Doors between rooms are statistically closed/opened more often than entrance doors, which is why the requirements for the reliability of the locking devices integrated into them are set at a higher height, but the requirements for burglary resistance are somewhat less.
In general, the magnetic lock in the door to the room should be stably designed for an increased number of locking / opening cycles. The locking magnets that exist today, for the most part, satisfy these requirements. Despite their small size, they are able to perfectly fix / hold the door. The basis of their action is that the magnetic strip mounted in the door attracts a metal element installed in the box (jamb). Most devices can only fix the doors in the “closed” position, but there are also models that automatically close the room, and a special electronic key is required to open.

In order to open the door leaf with a mechanical latch without much noise, you will have to very carefully press the handle so that the tongue enters the door body and carefully open the door. This operation can cause some discomfort, and will also lead to accelerated wear of the handle in the bar and the general “looseness” of the entire mechanism. The only advantage of a mechanical lock is a clear fixation of the door in the locked position, and only for a while before the wear process begins. In addition, such latches have significant disadvantages that emphasize the constructive unreliability of the entire mechanism as a whole:
If you do not install hinged doors, but install their sliding version, equipped with rubberized roller gaskets, then the process itself will cease to be noisy for some time. Unfortunately, like everything mechanical, the rollers can also fail, which will cause extraneous squeaks.Thus, in order to ensure reliable soundproofing in the room and opening / closing doors in the absence of extraneous noise, many homeowners install magnetic locks produced using innovative technologies.
In the simplest way, passive devices on magnets work. Their design is represented by only two elements that are attracted to each other by means of a magnetic field. Until the incoming one makes an effort by pulling the handle, the elements will be in a hitch with each other. However, in their design, passive models can also have mechanical parts. We are talking about a double degree of protection - until the handle comes to the lower position and the tongue is lowered, the door will not open. And even with the tongue down, the door will be held closed by magnets. In electromagnetic models, the principle of operation is much more complicated, because the presence of an electric current is required, with the help of which the door is held in the closed position. Voltage will be applied until the electronic key is applied. Through it, the current supply will stop for a short time and it will be possible to enter. It is worth paying attention to the fact that only those keys that have been programmed for this particular lock will work (which adds more reliability to the entire system).
Magnetic devices for constipation, in comparison with other options, can be used even at cold temperatures. In general, weather conditions have little effect on the operation of their parts. The main thing is to exclude the issue of power outages.Taking into account the fact that they do not have rotating/moving parts, their lifespan is much longer than that of mechanical devices. To increase the protective qualities, the lock can be provided with a special opening device powered by a magnetic key. The work of magnetic constipation is possible under direct ultraviolet rays, and with strong gusts of wind, and with heavy rainfall. This is not accidental, because magnetized metal with an anti-corrosion coating is used as working elements, which does not overheat and does not melt.
Among other things, a rechargeable battery can be integrated into the magnetic lock, capable of providing independent operation in the absence of power supply for 24 hours. This option is especially relevant for areas where problems with the supply of electricity occur on a periodic basis.
Most experts call the main advantage of these devices their long service life and increased degree of reliability. In addition, they can work in almost any conditions - the main thing for some models is a constant supply of electricity. The device itself functions without any extraneous sounds, it is easy to mount it in the door leaf and even provide it with a code panel. A subtle installation method is not able to spoil the surrounding interior.
However, there are also significant “cons”, these include the fact that a house equipped with electromagnetic locks may be unprotected when the power supply stops and the device is not provided with its own battery.It is also worth paying attention to the fact that if the lock is opened with a key, this does not mean that attackers will not be able to crack it - it is quite possible to make a replica from the original key card.
The described devices can be divided into several types:
Technical advantages of magnetic devices:
Technical disadvantages of magnetic devices:
On today's market, there is a large assortment of magnetic locks for interior doors. First of all, in the buying process, you should pay attention to the following parameters:
Without fail, the question of the load that the selected constipation is able to withstand must be resolved. For installation in plastic doors or fiberboard sheets, you can use a device adapted to a load of 100 - 150 kilograms. If the locking mechanism is supposed to be installed on massive iron / wood doors, then the load parameter should vary from 250 to 300 kilograms. Almost all electromagnetic locks can hold a load of 400 kilograms or more, so they are used on large and massive doors. In order for the purchased device to serve for a long time, it must have a high-quality protective coating. As a rule, these types of locks have an upper nickel or zinc layer. Also, the coating can be represented by a special film.
IMPORTANT! Painting the magnetic surface is highly discouraged due to the fact that its functional properties will decrease.
In principle, if the user has minimal skills in the field of joinery or carpentry, then installation will not be difficult. You will need the following tools to complete it:
Step by step work procedure:
Despite the fact that the devices in question are characterized by increased reliability and extended service life, situations may still arise in which they must be repaired or replaced. These include:
Most often, all of the above situations are a direct consequence of improper installation or the use of low-quality products. In cases where it is found that it was the mechanism itself that was produced with a low level of quality, then it is possible to fix the breakdown only for a short time (and soon it will have to be replaced completely). If the problem lies in the installation, then it is quite possible to fix it.
If a situation arises when it turns out that it is not possible to repair the lock, then the easiest way out is to purchase the same working model or a similar one that is suitable in size, shape and functionality.Thus, it will not be necessary to spoil the door leaf, making other niches and holes in it, different from those that have already been made.
In order for the magnetic lock to work in interior doors for a long time and with reliability, it must be operated by observing a few simple rules:
Thus, if the magnetic lock was made of high-quality materials, without marriage and correctly and correctly installed in the door leaf, while the conditions for its operation are observed, then it is able to serve the homeowner for more than a dozen years.

As current trends show, interior magnetic locks are gaining more and more popularity. The reasons for this are completely different - from ease of use to external aesthetics and high-quality functionality. In addition, it is magnetic interior locks that are an integral part of the "Smart Home" systems that are so fashionable today. By integrating them into such a system, they can even be controlled remotely. Also, the development of these devices is facilitated by the possibility of their modification - many different modules can be integrated into a single system with them, thereby protecting your home and its separate premises from unauthorized entry.
