Electronic park brake interface module, park brake controller and system

A park brake interface module for a vehicle, comprising:

• a park brake switch device comprising an electromechanical switch and an actuation member mounted to the electromechanical switch;
• and
• a feedback device providing feedback as to the state of a park brake of the vehicle comprising:
• a light pipe located adjacent to the electromechanical switch and extending to the actuation member for transmitting a light indicative of the state of the park brake;
• and
• a solid light lens located within the actuation member and movable with respect to the light pipe, the light lens having an arcuate portion at an interface with a surface of the light pipe and a flat portion at an interface with a front surface of the actuation member;
• wherein the actuation member comprises the front surface and a finger pad opposite the front surface;
• and wherein the actuation member is pivotally mounted to the electromechanical switch and movable in a pivot arc between a brake apply position, the brake apply position comprising the actuation member being pulled away from a front panel of the interface module at the finger pad, and a brake release position, the brake release position comprising the actuation member being pushed toward the front panel of the interface module at the front surface, wherein the arcuate portion of the light lens allows light indicative of the state of the park brake from the light pipe to be visible through the flat portion of the light lens at the brake apply position and the brake release position of the actuation member while maintaining a gap between the light lens and the light pipe as the actuation member is moved through the pivot arc.
