Multiple-gain electronic brake actuator with trigger point inertial sensor

摘要

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