Feature

●MAIN FUNCTION - The reed switch is an electrical switch operated by an applied magnetic field. Designed for use with alarm systems. Great for use in family and factory window, door. etc.This is a set of magnetic detecting switch used to protect doors and windows for the most part.
●SWITCH TYPE - NO means normally open: when the magnet separate, the circuit is conductive( light on ); when the magnet together, the circuit is not conductive ( light off ), NC means normally closed: when the magnet together, the circuit is conductive( light on ); when the magnet separate, the circuit is not conductive ( light off ).
●PREMIUM MATERIAL - High quality magnetic sensor contacts with strong magnetic, sensitive respond and long durability.Easy to install and use. A good replacement for the old contacts. Simple to install no hassles. Protective device monitors the opening and closure of doors and windows.
●RISK- GUARANTEE - You will get a full unconditional money back guarantee if you are not happy with this product .If you have any questions, please feel to contact us to get the most satisfactory results.
●433MHZ TRANSMITTING FREQUENCY - When the magnet is near it makes connectivity, when the magnet is removed connectivity is broken.Wired magnetic door/windows contact can be added to wireless/wired Alarm Systems.(some wireless system has wired zones).433MHz transmitting frequency, wireless connection.
