A control lever joystick has a main body member 11 with a mount at a lower end and a head portion 12 at the other upper end on which a plurality of switches, buttons or other control members C, D, G, H, I are mounted for operation by the thumb or fingers of an operator's hand. The main body portion carries an interchangeable hand grip portion 13 which extends upwards along the main body portion to be gripped by the operator's hand and which includes an integral lower support portion 23 which extends generally perpendicular to the main body member and which supports the lower edge of the operator's palm. Different hand grip portions 13 having differently shaped support portions 23 are provided so that an operator's thumb and fingers can be supported appropriately to operate the switches, buttons or other control members. The lower end portion 24 of the main body member 11 also extends generally perpendicular to the main body member and supports the lower support portion 23 of the interchangeable hand grip l3. The interchangeable hand grip 13 comprises a shell-like component which overlies and is detachably secured to the main body member of the lever. |
