Introduction
The magnetic reed switch is the electrical switch operated by the magnetic field, that controls the flow of electrical current in the circuit. The reed switch has two types. For the first type, when there is an applied magnetic field, the contacts become part of this magnetic circuit. Hence the contacts make the opposite poles and attract each other. Thus, called 'Normally open contact'. The second type of switch is closed in normal conditions and gets opened while the applied magnetic field. Therefore, called 'Normally Closed Contact'.
