Elektronische Pedale mit verbesserter Rückstellfeder.

摘要

An electronic foot pedal for outputting an electrical signal proportional to the degree a treadle (12) is pivoted. The electronic foot pedal has an improved spring arrangement for yieldably biasing the treadle toward its home position. Dual springs (50) are provided, independently mounted and supplementary to each other. Each spring has an adequate biasing force to urge the treadle to its home position. The springs are of a ribbon-like material that are wound into a flat spiral. The springs are subjected mainly to bending forces and have flexure as the treadle is pivoted to its pivotal limits.
