The lever (200) pivoted within a slot (140) in a preferably plastic housing (100) is indexed with a relatively rotatable plate (410) carrying a spring-loaded stud (452) whose axis (453) passes through the centre (211) of the pivot (210). The stud is pushed into a network of channels (112,114,118) in the surface of the housing with hollows (115,116) at the ends of the secondary channel (114). The other end (416) of the plate is constrained by the spherical tip (476) of a finger sliding in the guide (120).
