The Reed devices are electronic or Electro-mechanical components that work using the technology of the reed contacts, realised for the first time by the Bell.The Reed contact switch is a lamina (normally open) which closes in the presence of a magnetic field.
The reed contacts have found use in the production of various types of sensors.
There are two modes of use of these contacts:
simple pure contacts, for the detection of a magnetic field;
complex equipment, in which the reed contact is used as the transduction element.
In this guide I’ll show you how to use this switch to turn on an LED.

ABOUT THE SENSOR
Description: This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens. This makes for a great non-contact switch. This switch can carry up to 1.2A.
