Description: MC38 Wired Magnetic Contact Reed Switch for Door Window Security Alarm System Normally Open

There are two types of reed switches: “normally open” reed switches and “normally open” reed switches. The metal reeds on a normally Close switch stay Close when there is no magnet near the switch. In the presence of a magnetic field, the contacts of a normally-Close reed switch will Open. A normally-Open reed switch is Opened when it is not near a magnet; as a magnet is brought Open to it, a normally-Close switch will open.

  • Switch Type: NC(normal Open type), circuit is connected when magnet is near the switch.
  • 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.
  • Ideal for residential or commercial use. Designed to do embedded in door or window frame in door or window frames.
  • With double-sides tape design that for easily install.
