ABSTRACT:
A paper shredder with an auxiliary switch configured on an entrance of a top cover. A pressure rod of the auxiliary switch is sleeved in a spring and penetrates an inner side of the top cover, and further passes through an aperture defined in a flat plate, and thereupon compresses a contact plate; which then activates a contact switch to actuate a motor to rotate two rotary cutters. A spindle of a shaft lever configured on one end of the contact plate inserts into one end of a turning axle, and a paper shredder switch is configured on another end of the turning axle. Upon inserting paper into the entrance, the paper presses down on the paper shredder switch, and thereon activates the contact switch, which actuates the motor to begin shredding of the paper. Pressing the auxiliary switch initiates cleaning away the entrance of any shredded paper remnants.
