Van Haus Corded Angle Grinder (Glyne Gap TN40)

This has stopped working. I think the problem is the switch, which has been temperamental for sometime. It's the basic model (900w?), about five years old and only used about a dozen times. I have never replaced the cutting disc so all the others that came with it are untouched. So probably for someone with knack for fixing things or who just wants the discs.
