Switch machine refers to the important signal equipment used to reliably change the position of the switch, change the opening direction of the switch, lock the switch rail, and reflect the position of the switch.
Effect
(1)Switch the position of the switch to position or reverse as required;
(2)After the switch change to the required position, lock it, and avoid it being converted with the external force;
(3)It correctly reflects the actual position of the switch. The switch's pointed rail is closely attached to the basic rail, and corresponding representation is given.
(4)When the switch is crashed or is in the position of "four open" (two side rails are not closed tightly), the alarm and signal shall be given in time.
