Description:
The Magnetic Switch utilizing a magnetic reed switch, is designed for a wide range of applications. It consists of a magnet, which is installed on a door or window, and a magnet switch unit, which is installed on the frame. When the door or window is in the closed position, the created circuit is closed; when the door or window is opened, the circuit is open, which causes an alarm to be initiated. It detects magnetic fields to activate or deactivate devices based on their proximity, making it suitable for various scenarios. It is used in appliances like humidifiers, air conditioners, coffee machines, washing machines, and freezers, as well as automotive systems such as car counters, scanners, and electric irons. Additionally, it is applicable in fitness equipment like running machines and exercise bicycles, enhancing its versatility. The sensor’s robust design ensures reliable operation in diverse environments, providing consistent functionality. Its applications span from home electronics to industrial systems, making it a versatile solution for modern devices.
Features
- Select high-quality plastic materials, meet standards, and use more assured
- White electroplating surface, small and exquisite, light and easy to install, highly concealed
- After rigorous testing, even if the door sensor is in water, the signal is transmitted uninterruptedly
Application

What does a balanced magnetic switch do?
Balanced magnetic switches are used to monitor doors, gates, windows, or other access points into a secure area. The BMS typically consists of two separate units, each contained in a cast or molded lightweight housing to provide easy installation.
How does a magnetic safety switch work?
A magnetic switch is an electrical switch that closes or opens contacts in the presence of a magnetic field. That is, the switch remains on as long as a strong magnetic field is present and opens when the field is removed. Examples of magnetic switches include reed switches, Hall sensors, and electromechanical relays.
Is a magnetic switch worth it?
Yes. A magnetic switch is an electrical switch that makes or breaks contacts in the presence of a magnetic field.
What is a BMS switch?
Balanced Magnetic Switch (BMS): A security device used to monitor the opening and closing of doors and windows. It consists of a magnet and a sensor that form a circuit, which, when disturbed (for example, by a door opening), triggers an alert.
