DFRobot Magnetic Switch Door / Window Contact

The magnetic switch consists of an inductive end and a trigger. The inductive end is a reed switch connected by a cable, while the trigger is a magnet in a plastic casing. When the distance between the two parts is less than 1 cm, the reed switch is connected and detects the position change of an object. The magnetic switch is suitable for harsh environments and can be used in various applications such as door and window position limiters, smart toilets, car and electric bike anti-theft devices, and smart home. It is characterized by reliable performance, long lifespan, low power consumption, wide voltage range, and high operating frequency.
