The simple things in life turn out to be the hardest. I had a new kitchen put in last year in my Victorian house. The old kitchen gutted and completely rebuilt. A new elictrical ircuit was put in with stainless steel light switches. I need to get at the wiring behind one of the switches and whilst one of the screws will come out the other will not!! As the walls were rebuilt they put in the plastic back boxes that have the two red housings to take the screws. From memory these red housings can go backwards and forwards. The offeding screw just turns and turns it has come halfway out but although still turning will come no further, it doesn't go back properly either. I am using pliers to grip the head as I turn it but no good. I have enough room to get hacksaw blade on and cut through and whilst this will allow the front plate to come off I would then never get the rest of the screw out? Any suggestions greatly received!!
