    Abstract: A neutral start and backup switch is mounted on a collapsible steering column by screws and screw anchors. The anchors have a breakaway feature so that the switch will not unduly hinder collapse of the steering column upon some casualty to the vehicle. This feature is provided by ramp surfaces on the legs of the screw anchor which enter a hole in steering column such that upon enforced relative movement of the switch and column the screw anchors are cammed out of the mounting holes in the column. The anchors may be metal or plastic.
