I have a remote switch for the remote controlled signal and the connectors ofthe wires that go into it don't push in all the way. When I looked the centrehole in the switch it isn't as deep as the other switches I have which isstopping the centre post going all the way in. Is this normal? Should the wirehave a different connector on the end? Can you drill the centre hole to makeit deeper? I also have at least one point motor that has the same issue. Anyhelp would be great.
