Grounding Light Switch
Clean all the crud out of the box.  Remove the current switches.  Cut the 'strip length' to just at a half inch.  Pull the ground package out to be workable.  Get two lengths of #14 bare solid about 8" long.  Wire nut them into the existing ground package. Connect new ground wires to new switches on ground screws.  Plug in circuit wires.  Using care to dress wires to separate bare wires from live surfaces, install switches and plate.
