A pedal device, primarily for an electrically operated vehicle brake, uses a pedal pivotally mounted for angular movement relative to a base, a leaf spring attached to the free end of the pedal and stressed by being urged by angular movement against a surface of a bearing block, the location of engagement of the spring on the surface being progressively varied during pedal movement to obtain a predetermined ratio between pedal movement and pedal effort depending upon the location, and an electrical potentiometer arranged to be actuated by the pedal angular movement to produce an output proportional thereto. |
