ABSTRACT:
A signal transducing device comprising a first element having a contact surface with a conductive path, a second element having an arcuate contact surface with an arcuate non circular conductive path and being movable with respect to and engaging by rocking action the contact surface of the first element, the conductive paths of the elements electrically contacting each other at a location which is displaceable along their paths with the movement of the second element. Positioning means retains the elements for relative movement and actuating means moves and positions the second element with respect to the first element and controls the contact location of the elements, while connecting means electrically joins with the conductive paths of the first and second elements for providing an output signal determined by the position of one element with respect to the other.
