Abstract
The invention relates to a device for measuring the position of a movable member relative to a stationary member, the stationary member being one of the walls of a booster housing (14), and the movable member being a piston mechanism (16) dividing the housing into a front chamber and a rear chamber, comprising a movable first mechanism (42) which is movable together with the movable member (16) and the movement of which is detected in relation to a second mechanism (26) stationary relative to the stationary member (14). According to the invention, the stationary second mechanism (26) is fastened to the stationary member (14) outside the housing (14) of the booster, the movable first mechanism (42) sliding relative to the stationary second means (26), so as to vary at least one electrical quantity as a function of the position of the movable first mechanism (42) relative to the stationary second mechanism.
