Abstract
The present invention relates generally to a shutoff mechanism for shredders. The shredder has a shutoff button coupled to the on/off switch whereby activation of the shutoff button results in the on/off switch switching to the off position thereby shutting off power to the shredder. The shredder can also be turned off by the conventional means of sliding the on/off switch from the on to the off position.
