What is the reed switch?

The first Reed switch was established in 1936. It was the invention of W. B. Elwood in Bell Phone Laboratories. It is a specialized type of switch that works magnetically. This switch has the ability to lower the siren when the movement is detected as part of the burglary alarm. This is also commonly used with controls of electrical circuits and is an important device in the communication industry. The two -sea switch usually has open contacts that are closed during operation, referred to as (in) contacts. On the other hand, it has a three -dimensional type, a couple (not) and a few normally closed contacts that are referred to as (NC).

The switch is closed in a small tube that is controlled by a magnet or magnetic field. It works with the help of another magnet that is located within the switch. When the magnets make contact, they attract together and finish the electrical circuit. This results in a change in contacts to the opposite condition.

As the magnetic field decreases, the switch and its contacts with OKAffairs returns to its original state. The magnetically operated switch like this is normally mounted on the doors and windows to add protection to the house or company. The switch is small enough and discreet to mount in a house or office without being noticeable.

While the small size of the reed switch makes it easier to mount and operate, there are some disadvantages. For example, because it is small and gentle, it cannot maintain a large current voltage. Instead, the current can easily pass directly. Excessive voltage may cause the switch to sparkle when using. It is also known to overheat when used with heavy current. This can cause the switch to lose its source form.
