Abstract
This specification discloses an improved safety switch of a shredder. The paper outlet at the bottom of the shredder housing is provided with several switches around it, each of which is connected by a wire with another one in series to form a switch circuit. The switch circuit is connected through wires with a shredder control circuit to form s closed circuit. The switch is triggered by an external force, and the signal is transferred to the next switch. If the next switch is not triggered by an external force, the signal is interrupted and stopped. In other words, the switch circuit cannot form a closed circuit with the shredder control circuit and the shredder cannot function.
