A mechanical bin-full device for a paper shredder with a bin, having a curved, perforated T-blade sensor on a cylindrical body partially covered with a metal sheet. The T-blade is pendent into the bin. Metal contacts are placed on the paper shredder near the metal sheet, forming a switch, which is coupled to a motor control circuit for the shredder motor. The T-blade is pushed by paper shreddant and rotates the cylinder body as paper shreddant fills the bin. When the bin becomes full, the T-blade is positioned so that the metal contacts touch the metal sheet, closing the control circuit switch, and causing the motor to cease operating. The control circuit can include a microcontroller coupled to the motor, or a transistor-based driver coupled to a motor relay.
