Abstract
A capacitive electro-mechanical transducer for responding to both push and pull, for example in a road vehicle drawbar, involves axially spaced flanges (3) on the one force-transmitting member lying on opposite sides of a transverse portion (1) of the other member. The force is transmitted resiliently between the flanges and the portion, and there are capacitor plates (11) between the flanges (3) and the portion (1), so that on relative displacement the capacitance of one set of plates increases and that of the other set decreases. The plates are symmetrically disposed, e.g. of annular form, and they, or the dielectric (13) between them, can be wavy.
