Zusammenfassung:	The utility model discloses a lifting platform electrical circuit control switching device. The lifting platform electrical circuit control switching device comprises a rotating shaft connected with a reduction shaft of a reduction box used for rising and falling of a lifting platform, a rising touch ruler and a falling touch ruler which are arranged on the rotating shaft, a rising circuit which is closed when inducing with the rising ruler and used for cutting the lifting platform, a rising a proximity switch enabling the lifting platform to stop at a high position, a falling circuit which is closed when inducing with the falling ruler and used for connecting the lifting platform, and a falling proximity switch enabling the lifting platform to stop at a low position. By mutual matching of proximity switches and corresponding touch rulers, switching control of a lifting platform electrical control circuit is achieved. By cooperating with an on-site hydraulic thruster, steel feeding and steel discharging posit
