MULTIPLE-GAIN ELECTRONIC BRAKE ACTUATOR WITH TRIGGER POINT INERTIAL SENSOR

摘要

An electronic controller (20) for outputting pulses of current to actuate towed vehicle brakes includes a trigger point inertial sensor (24) for varying the gain thereof. The trigger point inertial sensor (24) includes a switch (51) connected to the controller (20) for switching the gain between two levels. In the preferred embodiment, the inertial sensor (24) and switch comprise a mercury switch (83, 88) supported on a platform (44) which is rotatable to adjust the switching threshold of the inertial sensor (24), and to adjust for the mounting position of the brake control.
