user60421: 
Hello sir , so can i cut the switch from the picture and connect the wires to my relay module ? Im sorry because im still learning . Thank you !

user4143: A relay is nothing more than a switch - but instead of your finger controlling it, it's controlled by an electromagnet.
The relay can perform the exact same function as the switch on that cable.  In the image you have posted you would use the right-hand two screw terminals (middle is "common", right is "normally open") to replace the switch.

user60469: You can refer to this to cut the switch 
If you are a beginner, you can get started with Relay here
NOTE: It's dangerous and can cost your life. Please be careful when using Relay with 220 VAC
