Abstract
Abstract An alarm system is provided for use on motor vehicles to monitor the condition of the vehicle''s shock absorbers. The system includes a spring-loaded switching device mounted to each shock absorber and connected through a circuit to an alarm such as a light or buzzer which may be installed on the vehicle''s dashboard. The switching device closes if the shock absorber telescopes beyond its normal operating range.
