hi

sister has bought a house and we have been decorating for last 2 weeks or so!

Today in her d-stairs toilet i had to move the light socket and switch so i could paper up the walls.

I am looking to replace the light switch with a pull cord.

at the moment the wiring is as follows:

red and black wires into light socket

and then one solitary live wire going from socket to light switch

in order to replace the light switch do i replace it with a one way pull cord switch with wiring remaining as it is (want to check to see if the wiring set up is correct)

thanks
