An inline reed relay comprises at least one reed assembly, at least one pair of metal pins, a housing and a control pin disposed on the housing. The reed assembly comprises at least two reed switches, each having two pins. The metal pins are respectively connected to the two pins of the reed switches. One end of each metal pin extends out of the housing. The inline reed relay allows the reed switches to be integrated through the injection molded housing, and the reed switches are connected to an external circuit board via the metal pins, because the metal pins can be maintained a fixed shape and difficult to deform. The processing size and position tolerances of the inline reed relay can meet the requirements of mechanized automatic welding, thereby improving welding efficiency and production assembly efficiency and reducing labor costs.
