Structure of Magnetic Reed Switch

Magnetic reed switches are sealed in glass tubes by two magnetic reeds (usually composed of iron and nickel). The two magnetic reeds are overlapped, but there is a small gap between them. The external appropriate magnetic field will make the two magnetic reeds contact.

The contacts on the two reeds are plated with a layer of hard metal, usually rhodium and ruthenium, which greatly improves the life of switching times. Nitrogen or some equivalent inert gas is usually injected into the glass tube, and some magnetic reed switches will make the interior into a vacuum state in order to improve the performance of switching voltage.

Why Purchase FBELE Reed Switch

low cost
Low Cost

FBELE’s automated production and testing reduces product costs

small size
Small Size

Because of its small size, reed magnetic switch can be applied to electronic products with limited space.

good consistency
Good Consistency

The automatic production of FBELE company ensures the excellent consistency of the reed switch

long life time
Long Life Time

The contact has excellent corrosion resistance and wear resistance, long service life and stable switching action.

The Advantage Of Reed Switch Sensors

The contact is sealed in the glass tube with inert gas and will not be affected by the external atmosphere.

The action answers quickly. The action system and circuit are located on the same axis, which is suitable for application products with high frequency transmission. Small and light. The contact has excellent corrosion resistance and wear resistance, long service life and stable switching action. Combined with a permanent magnet, a non-contact switch can be formed economically and simply.


Performance of Reed Sensor

Magnetic reed switch is a unique technology. Its fully sealed characteristics make it can be used in almost all environments. Although the structure of magnetic reed switch is simple, its manufacturing process includes a number of processes. In recent years, the size of magnetic reed switch has developed from about 50mm (2 inches) to as thin as 6mm (0.24 inches). The emergence of these small sizes enables it to be applied to more fields, especially to meet the needs of RF and fast time domain.

What does customer say about FBELE Company


We cooperated with FBELE since 2018,what ever time I send massage to FBELE, I allways get their quickly reply even in middle ninght in BeiJing time, it seems we have no time difference with FBELE,It’s really amazing,it really very good service!


We know FBELE in June 2021 ,we are new client,

When I first bought FBELE products, I was worried about the quality, but after receiving the first batch of trial order goods, my doubts were dispelled. FBELE product quality is very good! We will place big order this year, thanks for FBELE!

Genaral Questions About Reed Switch

Why does the reed of reed need nickel / iron and 52% nickel?

The magnetic field affects only ferromagnetic metals. Nickel and iron are ferromagnetic. 52% nickel is critical because its coefficient of thermal expansion perfectly matches the expansion rate of glass.

Under what conditions will the reed of the dry reed be attracted?

In two cases, the permanent magnet will be used: the basic operation of the dry spring switch under the magnetic field generated by the permanent magnet. The two reeds have opposite polarities and generate enough suction between them to contact each other. Use of external coil: place the magnetic spring switch at the center axis of the coil. The magnetic field is the strongest in this part. The two dry reeds are of opposite polarity, generating enough suction between the two reeds to contact each other.

What is the difference between different release ampere turns (rat) of two reed switches?

When two identical magnets are removed from the two closed reed switches, they have the same operation, but different versions, higher versions, which are sensitive to the magnetic field, will open first.

how is the reed connected to the rated voltage and switching current of the switch contact?

The switching voltage and switching current shall not exceed the maximum rated value, and the product of current shall not exceed the maximum contact rated watt.

What is the dry reed seal?

There are three types of sealing strip seals: glass glass seal, glass metal, metal to metal seal In these seals are meant to have zero porosity, i.e. no leakage at the molecular level.
