A signal transducing apparatus comprising first and second elements movable with respect to each other and each having first and second ends and a conductive path, the conductive paths of the elements electrically contacting each other at a location which is displaced along their paths with the relative movement of the elements. A spring unit movably retains the second element having a first end fixed with respect to the first element and a second end secured with the second end of the second element, the spring unit urging the second end of the second element in a predetermined direction with respect to the first element and urging the first end of the second element in the direction toward the first element. Actuating means positions the second element with respect to the first element by moving the second end of the second element in a direction opposite to the direction in which it is urged by said spring unit, and 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.
