Description: MC38 Wired Magnetic Contact Reed Switch for Door Window Security Alarm System Normally Open
Pair MC38 MC-38 Wired Magnetic Contact Reed Switch For Door Window Security Alarm System NC Normally Open Magnetic Switch Surface Mount Door Sensor Home Alarm System Sensor For Arduino
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.
