ABSTRACT:
Vehicle parking brake comprising a hand lever (1), a support (2) provided with a pin (6) on which the lever is pivotally mounted, a cam (7) mounted on the pin and connected to rotate with the lever, the cam being connected to braking means. An electric contactor (15) cooperates with the lever and is part of an electric circuit for lighting up an indicator light (17). The contactor comprises a conductive metal blade (19) and an insulating covering (21) surrounding the blade. End portions (19a, 19b) of the blade extend out of the covering. The contactor is so positioned relative to the cam that, in the lower position of the lever, the electric contact between a free end portion (19a) of the blade and the cam is broken and, on the contrary, established beyond a given angular position of the lever up to an upper position of the lever by a rubbing of the cam on the free end portion of the blade. The contactor has the advantage of great simplicity as it is reduced to two parts and is consequently inexpensive and moreover more reliable owing to the self-cleaning rubbing contact between the blade and the cam (7).
