Patent ID: 7414212

Claim:
An emergency stop switch (ESS) of a shredder disposed in a preformed hole on the top cover of the shredder and protruding from a top cover surface for the convenience of switching, the ESS comprising: a switch with fwd, off, and rev modes; a brake, which is disposed on the switch and has a control part protruding from the shredder top cover for switching among the different modes and a positioning part for assuring the switch mode; a positioning base, which is disposed on a bottom surface of the shredder top cover opposite to the position of the positioning part for assuring the switch mode; and a restoring part, which releases stored energy to push the switch from the fwd or rev mode to the off mode; wherein when the switch is in any of the fwd or rev mode and the controlling part of the brake that protrudes from the shredder is under a pressure to move downward, the positioning part of the brake departs from the normal fixing position of the positioning base so that the restoring part pushes the switch back to the off mode.
