Yes. Stick the switch on the output of the PIC and the RX module on the input. PIC reads received signals from the RX and turns the switch on and off accordingly.
Of course, you also need a PIC and TX module (or some other way to communicate with the TX) in order to send signals in the first place.
on what module do i need to stick the switch on the output of the PIC? at the PIC and TX module? I must use switch which will serve as a controller for sending data to the RX cause i want every switch should perform different task like turning servo motor to left and right.
