Three-phase motor using the limit switch for inverting circuit

As shown in the figure, two limit switches SA1 and SA2 are used to achieve the automatic control of reciprocation. It utilizes the use of motor to drive mechanical impact limit switch SA1 to achieve forward run’s self-closing (KMF’s off). Meanwhile, the closure for SA1’s interlocking contact is to achieve reversal self-opening (KMR’s closure). And vice verse.
