ABSTRACT:
An encoder device encodes angular position in the form of electrical signals in dependence on the position of a rotatable member in relation to a series of discrete fixed contacts disposed about the axis of rotation of a rotatable member. A series of discrete fixed contacts 2a, 2b, carried by a panel 1, form a first group of contacts of a flexible switch structure which also has a second group of contacts 9 carried by a flexible sheet 7 and arranged such that each contact of the second group is located opposite to, but spaced from, one of the series forming the first group of contacts. An intermediate sheet 8 is sandwiched between the panel 1 and flexible sheet 7 and is apertured at 10 in the region of the contact sets 2a, 2b and 9. The rotatable member carries a switch actuator 14 which operates to close any of the oppositely disposed first and second contact sets, in dependence upon its angular position, the switch actuator being such that either one contact set is closed or two adjacent contact sets are closed for any angular position of the rotatable member. The output is derived from terminal areas 6 on the panel 1.
