Therefore, the mechanical switch creates an open or closed electrical circuit. Switching method. For a reed switch, if the magnet is close to the reed switch it creates a closed circuit (electric current can flow). Therefore, if the magnet moves away the reed switch will create an open circuit (no electric current can flow).
