Reed Switch 2 x 14 mm Normally Open 10PCS

Reed Switch 2 x 14 mm Normally Open 10PCS - Do you need non-contact switching within your project? Then you may consider this sensor. A reed switch is an electromagnetic switch that controls the flow of electricity in a circuit. They are made from 2 ferrous reeds, positioned so that they are not touching. It is in a tube-like enclosure made of glass. When near a magnetic field, it pulls one of the reeds towards the other. That they are touching, so the signal on the other end flows. This switch can hold up to 300V switching voltage and has a minimum breakdown voltage of 150V. The contact rating is limited to 10W, with the max switching current of 0.55A. It also has a fast bounce time of 0.25ms with a release time of 0.35ms max. You could use this in projects with magnetic field detecting.

Important Factors about Reed Switch

  • Normally Open Contact Reed Switch 2 x 14 mm Magnetic Control Switch.
  • The two magnetic pins inside the button pull together when it is subjected to a magnetic field, closing it. The Reed Switch separates and opens when the magnetic field is eliminated. This works fantastically as a non-contact switch. Up to 1.2A can be carried by this switch.
  • This compact and user-friendly module is suitable for a range of climatic settings. In the temperature range of -50°C to +140°C, it performs quite dependably.


  • Compact Module
  • Very user-friendly
  • Straight circuit connection

Types of Reed Switch

The two basic and comment types of Reed Switches are "usually open" and "normally closed."

Two ferrous reeds, such as those composed of a nickel-iron alloy, are placed such that they are not touching in a typically open switch. One of the reeds is pulled toward the other until they are touching when a magnet is pushed close to the switch, completing the circuit.

When the magnet is removed, the reeds return to their initial position and the circuit is broken.

An electrical circuit is complete and the device is "on" when there is no magnetic field, which is the reverse of how a usually closed switch operates.

The reeds resist one another and separate, breaking the circuit when a magnet moves close to a switch or the switch is pushed close to a magnet.

In a third configuration, there are three contact points as opposed to just two. In this setup, a common lead that can switch between two contacts also flows with the current.

Until a magnetic field is applied, the single lead will be in touch with one connection in its normal position. Then, the similar lead will be in connection with the other contact. The common lead returns to its initial position when the magnetic field is released.

Advantages of Using Reed Switch

Using magnetically actuated reed sensors has several benefits:

  • Including the fact that there is no mechanical wear and tear on the switch because no physical pressure is applied to it.
  • It is possible to design sensors that are sensitive enough to be hidden deep inside an assembly and still be triggered by a subtle, moderately powerful magnet.
  • There is no need for voltage because they are magnetism-triggered.
  • Comparing reed switches to mechanical switches, they are exceedingly small.
  • Reed switches' contacts are shielded from air corrosion since they are enclosed in a glass tube.
