In an electronic control system for controlling the setting of two or more continuously variable parameters, the system comprises a hand operated lever (1) and electronic processing means (14) having an input from the lever (1) and output means for outputting a signal or signals representative of the said continuously variable parameters, characterised in that: a) the lever (1) is arranged in a gate having two substantially parallel slots (3-5) and a transverse slot (6), the position of the lever (1) in each of the two parallel slots being substantially continuously variable and corresponding to a desired value for one or more of the said continuously variable parameters; b) the processing means includes means (14) for storing a record of the position of the lever (1) in one of the said slots after the lever has been removed from the slot. <IMAGE> |
