The relays should work.  Most relays are just too current hungry for the PIC
pins, so it would be a good idea to have a transistor switch to operate it.
Also you will need a reversed biased diode across the relay to stop the high
voltage back EMF reaching the PIC and transistor when the relay is switched
off.
