ABSTRACT:
A depression sensor for an electronic ignition advance device for an internal combustion engine especially intended for use in a motor vehicle, the sensor being of the kind having a membrane which in use is deformable in response to the value of said depression, wherein the sensor comprises resistive means having an ohmic value which varies in accordance with the force applied to said means, and an electronic control circuit controlled by said resistive means so that variations in the value of said depression applied to the membrane will vary the force applied to the resistive means and consequently will vary an output voltage of said electronic control circuit.
