Paper shredders have switches that prevent the shredder from operating when the top is not mounted on the basket. The middle photo shows a small slot on the side of the unit. The switch is inside that slot. A small piece of metal attached to the basket (shown at right) flips the switch when the top is mounted on the basket.
