Reed Switch

Reed switches are a type of electrical switch that is commonly used in various electrical and electronic applications. They are part of the supply class "Switches" in the supply group "Electrical and Electronic Equipment Components."

A reed switch consists of two ferromagnetic reed contacts enclosed in a glass tube filled with inert gas. These contacts are typically made of nickel-iron alloy and are hermetically sealed to prevent contamination. When a magnetic field is applied to the switch, the contacts come together and complete an electrical circuit. When the magnetic field is removed, the contacts separate and break the circuit.

Reed switches are known for their reliability, long life, and ability to switch both low and high voltages. They are commonly used in applications such as proximity sensors, security systems, automotive electronics, telecommunications, and many more.

One of the advantages of reed switches is their ability to be activated by a magnet without any physical contact. This makes them ideal for applications where a non-contact switch is required, or where the switch needs to be sealed to protect it from environmental factors such as dust, moisture, or corrosive substances.

Overall, reed switches are versatile components that offer a reliable and efficient solution for various electrical and electronic applications.
