An automobile speed control system of the vacuum actuated type having a unitized housing embodying actuator, modulator, electronic components and inductive position feedback means. Electrical connections into the hermetically sealed expansible actuator, and noise caused by feedback potentiometer wear are eliminated. Valve means within the actuator are operated by magnetic forces generated externally to the actuator, thus eliminating electrical connections. The feedback means comprise a metallic body sealed in the actuator and movable therewith and an inductor external to the housing arranged so that its inductance will vary according to the position of the metallic body.
