1. NO NC Switch: The magnetic switch has a normally closed function. When the two parts are combined, the switch is turned on, and when they are separated, the switch is turned off. The normally open function is the opposite.

2. Application: The magnetic contact sensor can be added to an existing wired alarm system and is suitable for wooden doors or windows. It is ideal for protecting doors.

3. High Sensitivity: The use of high magnetic magnets and reed switches makes the magnetic contact switch more sensitive and effective.

4. Safe Material: The magnetic reed switch uses ABS construction, fire retardant and flame retardant, which is safer and more convenient to use.

5. Easy Installation: The magnetic door switch uses surface mounting and screw installation, making it convenient and reliable to use.
