The automatic switch comprises 4 rows of static nodes and 2 rows of movable contacts, and each row of movable nodes is switched between 2 rows of static nodes so as to realize the connection and disconnection of a circuit.
In the turnout unlocking process, the original representation circuit is disconnected by the automatic shutter node, and the action circuit ready for reversal is connected; after locking, the automatic switch node automatically cuts off the motor action circuit and turns on the indicating circuit; in addition, the automatic switch also supervises whether the whole process of the switch machine conversion is completed as required in the working process of the switch machine, and the automatic switch is matched with the indication rod to uninterruptedly check the switch-on position of the turnout and the close contact state of the switch rail; secondly, the automatic shutter also interrupts the switch indication circuit when a switch is squeezed.
