ABSTRACT:
A braking circuit for an electric motor includes a braking device for being connected in a circuit for braking the electric motor, a braking switch including first and second changeover switches for switching between a motor mode and a braking mode, and a control device. Switching contacts of the first and second changeover switches are switched between a first position for contacting, respectively, first stationary contacts of the first and second changeover switches in the motor mode, and a second position for contacting, respectively, second stationary contacts of the first and second changeover switches in the braking mode. The control device is coupled to the first and second changeover switches for controlling the switching between the motor mode to the braking mode so that when switching between motor mode to the braking mode, the switching movement of first changeover switch, which is closest to the power supply, is delayed with respect to the switching movement of the second changeover switch, and when switching from the braking mode to the motor mode, the changeover switches move essentially synchronously and simultaneously.
