The magnetic latch is designed to hold the door closed. It is easy to install, durable, and wears out slowly. Advanced models can serve as a door closer. The device can be installed on the door with your own hands.
How are magnetic latches different from regular latches? They use a unique physical phenomenon to hold the door closed. Non-mechanical engagement of the holder parts is used, as happens in conventional latches. The door is held closed by the force of interaction between a permanent magnet and the metal.
The device consists of two main parts:
This holding device consists of only 5 parts and has no moving parts. It securely fixes interior doors and cabinet doors. The simplest design magnetic door latches are small in size, invisible, and very reliable.
Designers created more complex models. They are equipped with a floating magnet that extends at a certain position of the door and disappears when opened. There are devices with push opening. To open such a latch, you need to press a button that moves the magnet away from the bar.
The physical principle underlying the operation of the device gives it the following advantages:
Magnetic latches for interior doors have a number of disadvantages. Complex models with advanced functionality are still significantly more expensive than their mechanical counterparts. With increasing popularity due to mass production of products, manufacturers will inevitably reduce the price.
In addition, a strong magnetic field may have undesirable effects on precision instruments such as mechanical watches, pacemakers of older models.
Experts classify magnetic mortise latches according to the following characteristics:
According to the installation method there are:
Structurally, the following types are distinguished:
They stand apart electromagnetic locks, in which the magnetic field is created not by a permanent magnet, but by a powerful inductor through which electricity. Such locks require a constant power supply and are used mainly in enterprises, offices - anywhere where access to premises needs to be controlled. They connect to centralized system management. Such locks open after the user is identified by bringing a magnetic card to the reader or by biometric indicators.
The operating principle is based on the physical attraction of magnetic materials (bar) to a source of constant magnetic field(magnet). Magnetic materials are alloys of iron with other metals. Permanent magnets made from ferromagnetic alloys. The castings are exposed to a strong magnetic field, causing them to become magnetized, becoming a source of constant attraction.
The magnetic field acts at a short distance (5-25 mm), so the blade must be brought close enough to the bar.
Attention! Critics of magnetic clamps often claim that over time, the magnet supposedly loses its properties. Engineering tests have demonstrated that the field reserve in a modern magnet will last for 30-50 years. The door will probably have to be replaced.
The magnet is little affected by ambient temperature and humidity. The absence of moving parts operating under load ensures high reliability, low wear, and long product life.
Devices based on attraction are extremely unpretentious in operation. They do not require periodic maintenance, cleaning, or lubrication, like mechanical ones. Typically, the manufacturer puts grease into the product, which is enough for the entire service life.
This makes the devices indispensable for use outdoors, for the entrance doors of houses, and auxiliary buildings. They are suitable for doors to a balcony, loggia or unheated veranda.
However, in more complex structures with a handle, the moving elements are still used. It is unlikely, but possible, that they will require replacement. Therefore, the device must be secured so that it can be removed. It is not recommended to glue the latch to epoxy or other particularly durable compounds. In this case, when dismantling the latch, it will have to be torn off with part of the canvas or jamb.
Important! It is necessary to choose the correct dimensions of the mortise product, especially if the canvas is decorated with inserts made of glass or other materials, or with relief carvings. The entire hidden mechanism must fit before the insert; you still need to leave 10-15 mm of margin to maintain the strength of the canvas. The width of the mechanism should also leave at least 8 mm to the left and right of it.
The metal strip of the simplest latches can also be subject to corrosion. It should be inspected periodically, and if signs of rust appear, it should be removed for touch-up.
Magnetic latches are becoming increasingly popular among homeowners. This is due to their reliability, ease of installation, and quiet operation compared to mechanical ones. You can install such a device yourself.

Reviews:
Mikhail, Rostov-on-Don
Today, exactly a year has passed since the installation, the “Bear” doors will be installed. It was not easy to choose, I discussed this issue on all forums. I thank those people who advised me good company. To find information, I had to go through all the reviews. After all, both Chinese manufacturers and several of our domestic craftsmen took part in the disputes. I opted for an advantage. And I advise everyone, if you are looking for doors, then listen to the opinions of those people who have used them for a year or two, and did not buy them just yesterday and are in a hurry to show off a new thing. “Bear” serves for a long time, this has already been verified.
Roman, Voronezh
And I bought the “Bear” doors only yesterday, but they are so beautiful that I can’t contain my emotions. It’s a little unexpected to get such a luxurious item and free service for such “pennies.” Good luck everyone, and remember, price does not always indicate quality!
