13. The controller of claim 11, wherein the face shell is provided with an outlet through which the set of communication lines passes; or the bottom cover is provided with an outlet, and the communication line group penetrates through the outlet.

14. The controller according to claim 12 or 13, wherein the communication line set is a flat cable, a flat cable terminal is disposed at one end of the flat cable, the flat cable terminal is connected to the connection terminal, and the flat cable and the outlet are sealed by a sealant.

15. The controller of claim 6, further comprising a cover membrane disposed on the bottom exterior surface of the face housing, the cover membrane having a shape that conforms to the shape of the bottom exterior surface of the face housing.

16. The controller as claimed in claim 15, wherein the face housing is provided with at least one key hole corresponding to the micro switch, the micro switch at least partially protrudes from the key hole, and the cover film is provided with a bump key corresponding to the key hole.

17. The controller of claim 16, wherein the communication assembly further comprises at least one relay disposed on the PCB board, and the indicating assembly comprises at least one operating status indicator light connected to the relay and at least one switch indicator light connected to the micro switch.

18. The controller of claim 17, wherein the front housing has at least one first light-transmitting portion and at least one second light-transmitting portion, the first light-transmitting portion is used for transmitting light of the operation status indicator light, the second light-transmitting portion is used for transmitting light of the switch indicator light, and the cover film has light-transmitting holes at positions corresponding to the first light-transmitting portion and the second light-transmitting portion.

19. The controller of claim 18, wherein the first light transmission portion and/or the second light transmission portion is a light transmission through hole or a thinned light transmission structure.

20. A control as claimed in any of claims 3 to 5, wherein the face shell is further provided with at least one fixing aperture, the fixing aperture being arranged to accommodate the mounting of a threaded connector.

21. The controller of claim 20, wherein said front cover is provided with at least one hollow portion, said fixing hole being provided in said hollow portion.

22. The controller of claim 20, wherein the at least one securing hole is disposed outside of the watertight slot.

23. The controller of claim 21 or 22, further comprising an orifice cap disposed in the fixation orifice.

24. A signal control system comprising an actuator and a controller according to any one of claims 1 to 23;
