Magnetic, Reed SwitchesMagnetic and reed switches are types of switches that are activated by a magnetic field. A magnetic switch, also known as a magnetically operated switch, is a switch that is activated when a magnet is brought close to it. This type of switch is commonly used in applications where a switch needs to be activated from a distance, such as in security systems or automotive applications. A reed switch, on the other hand, is a switch that is activated by a magnetic field passing through a sealed glass tube containing one or more reeds. This type of switch is commonly used in applications where the switch needs to be sealed from the environment, such as in underwater or hazardous applications. Both magnetic and reed switches are useful for a variety of applications, and are often used in electronic circuits to provide a convenient way to activate or deactivate a circuit.
