摘要： There is disclosed an improved mounting bracket kit for providing a fail-safe actuation of the pull-plug or release pin of a conventional break-away safety switch. The bracket is suitable for use either as a retrofit to improve the reliability of operation of existing switch installations or for use with new original equipment. The mounting bracket kit is such as to provide support for both ends of a conventional pull-plug switch housing with respect to the trailer chassis and to provide a guide for the cable leading to the release pin of the switch which guide is also supported with respect to the trailer chassis and is dimensioned and positioned so that the cable guide acts as a pivot point for the cable ensuring that the pull of the cable on the release pin will be along a straight line coinciding with the longitudinal axis of the pin or plug so that the release pin will not jam in the housing if the towing vehicle and trailer assume angular relationships other than that normally intended during the break-away action. Failure of the emergency breaking mechanism due to such off-axis components of cable pull which has occurred in the past is thus obviated.
