As I was trying to attach one of my 4 wires that controls that switch,I noticed right under the bolt that tightens down your wire's that there appears to be a kind of tab, that I am assuming, holds down the wires and keeps them in place once you tighten the wires down.I noticed,in one of my 4 slots that I have to put the wires into,that one did not have that.If I am suppose to have that under that bolt,what would be the part number so I can order some?
Thanks
