A foot pedal controller (1) comprises a pedal (2) to which is attached a lever (3) pivotally mounted both in a mounting flange (4) and an anchor plate (10). Downward force applied to the pedal (2) causing pivotal motion of the lever (3) in an operational sense is resisted by a tension spring (14) connected between the anchor plate (10) and the lever. A flexible cable (18) comprises a core (19) translatable within a casing (20). The core (19) is operatively attached to the lever (3) by a retaining clip (26) which is snap fitted to the lever (3). The casing (20) is secured against translational movement to the anchor plate (10) by a plug-in cable hub (38) having a flange (40) abutting one side of the anchor plate and a pair of spring arms (45) which will deform radially inwardly when the cable hub is pushed into a receiving aperture (47) in the anchor plate and then spring radially outwardly to abut the other side of the anchor plate. The core (19) can be operated by the foot pedal (2) alone by having a lug (22) with an enlarged head (22) engaging in a countersink (32) in the retaining clip (26). Alternatively, a hand control can be fitted as well in which event the core (19) would be extended through the retaining clip (26) and a second casing would encase the core to a hand control member and have one end seat in that countersunk (32), by which either the foot pedal (2) or the hand control member can be selectively used to translate the core in a pull mode. |
