What does this part actually do? I was cleaning up my accelerator linkage a couple of days ago, and noticed that the arm on the microswitch actually rides up on top of the linkage arm and doesn't actually "click" the switch. I tried bending the arm down, but there's too much play in the joint, and it doesn't stay in contact with the side of the linkage.

thanks,
anthony
