A KEM-1 B, magnetically controlled contact (reed switch) is an electric device that changes the state of an electric circuit by mechanically opening or closing it when a control magnetic field acts on its elements, combining the functions of contacts, springs, and sections of electric and magnetic circuits.
The principle of operation of KEM-1 B reed switches is based on the use of interaction forces arising in a magnetic field between ferromagnetic bodies. In this case, the forces cause deformation and displacement of the ferromagnetic current conductors of the electrons.
