What is the main role of the magnetic switch?

This article tells us about the main functions of the magnetic switch. First, the magnetic switch is mainly composed of two parts: the switch and the magnet. The switch part is connected by the reed switch through the lead wire. The magnet part is composed of the corresponding magnetic field strength. The magnet is encapsulated in a plastic or alloy casing. When the two are separated or close to a certain distance, the switch is opened and the position of the sensing object is changed. The door magnetic system is a safety alarm system, and the door is magnetic and the window is magnetic (the principle is the same). , the shape is different). Door magnet/window magnets are not easy to see if they are not noticed.

The so-called door magnet/window magnet is actually the abbreviation of the magnetic switch and the window magnetic switch. It consists of two parts: the smaller part is a permanent magnet, and there is a permanent magnet inside to generate a constant magnetic field. The larger one is the door. The magnetic body has a normally open reed switch inside. When the permanent magnet and the reed switch are close together (less than 5 mm), the magnetic sensor is in the working state, and the permanent magnet leaves the reed pipe at a certain distance. After that, it is in a normally open state. The magnets and the reed switches are installed in the door frame (window frame) and the door leaf (window), which are basically flush mounted (also surface mounted), so it is not very difficult for industry professionals to notice this. You can open the door and the external window. Look at the window frame at the top of the door and the outer window of the door. You can see the circular, usually white, elemental parts. In fact, this is the so-called door magnet and window magnet. .

The main function of the magnetic switch is only four words: convenient, anti-theft.
