Quoted from TDEX:
ok! I cleaned the switch with isopropyl alcohol it doesn't seem to be sticking,however I noticed a thin strip of metal that just dangles loosely. looks like a leaf switch. if I shake the table a little it causes the drop target to malfunction. my question is
is that strip of metal supposed to be so loose?
Something may be broken or loose. Take a nice high resolution photo of the dangling metal piece and post it in this thread and I am certain that you will get the help that you desire from this group.
