An automotive inertia switch including a switch body which houses a movable plunger weight; a button guide structure with a cylindrical nest, a switch reset button, a wiper contact, and a compression spring. Switching action is caused by the vertical movement of the weight. In an untripped state, a tip of the weight is spring biased by the compression spring into the nest. In response to a rapid change in the acceleration of the vehicle, e.g. a crash, the tip is dislodged from the nest and the weight is forced by the spring to move upwardly against the button. Vertical movement of the weight causes the wiper contact, which is in pressing engagement with the opposite end of the weight, to move between switching positions to make and break electrical connection of a common terminal to the fuel pump or a switch status indicator. The tripped status of the switch may be indicated by the switch status indicator, or by visual observation of the outward projection of the button. The switch may be reset by simply pushing the button downward to force the tip back into the nest.

Automotive inertia switch

An anti-lock braking system which is adaptable to installation in a wide range of vehicles by means of a self-adjusting connecting linkage between the brake and the control system for anti-lock braking. The brake pedal is linked to the control system by a latched member which releases to permit the linkage to assume the appropriate length for the particular vehicle. The linkage includes frictionally engaged elements which move relative to each other as required and the braking system includes a hydraulic circuit which prevents depletion of hydraulic fluid.
