ABSTRACT:
Active protection system for a paper shredder, which includes an upper cover and a shedder plate on the upper cover. The paper shredder plate includes a touch structure, which engagingly interacts with a preferential power supply switch. When closed, the shredder plate prevents contact with the shredding blade. When opened, the shredder plate both initiates shredder normal operation, and prevents feeding of unexpected items into the shredder making accidental contact with the shredding blade. When an unexpected item contacts the safety structure, beneath the paper shredder plate, the protection system switches off the shredder power supply.
