Arrangement to warn of braking or swerving of a vehicle

摘要

A metal disc is mounted at the top of a wire spring so that hard braking or swerving causes movement of the disc to complete a circuit energising the hooter and hazard lights or the hooter and head lights. A rear hooter and rear fog lights may also be energised. The disc is mounted within a plastics cylinder carrying a front contact to sense braking and side contacts to sense swerving. The separate contacts may alternatively be omitted, the cylinder then being of metal and the disc position being vertically adjustable to vary the effective length of the spring thereby adjusting the sensitivity of the swerving/braking sensor, (Fig B).
