Abstract
The invention proposes a master cylinderwith a device for detecting actuation of a braking system. The detection device is fixed to a bodyof the master cylinderat a pressure chamber. The detection device comprises a magnetic circuitable to be opened and closed by a moving magnetic piece. The moving magnetic pieceis, for example, fixed to a pistonof the master cylinder. Actuation of a brake pedal causes the pistonand the moving pieceto advance in the master cylinder. The magnetic circuittherefore changes state (opened or closed). The change in state of the magnetic field switches the brake lights on and off.
