The present disclosure discloses an inductive series switch control system. The control system includes several control modules that are connected in series, a first output inductive switch, and a second output inductive switch. Each control module is independently connected with an output interface, and each output interface is connected to a light-emitting diode (LED)lamp of a stair lamp; every two adjacent control modules are connected through three lines that are respectively a positive circuit, a negative circuit, and a signal circuit; the first output inductive switch is electrically connected to the first control module in the serially connected control modules; the second output inductive switch is electrically connected to the last control module in the serially connected control modules; and the positive circuit and the negative circuit between any two control modules are connected to a power input end.
