Abstract
An automotive flasher switch having two terminal pins is disclosed. A relay having a conductive yoke and having a conductive, spring mounted armature, is connected to one terminal. A contact, supported by the armature, intermittently engages the other terminal during cycling of the relay. During cycling of the relay, current passes along a conductive path in the relay. A circuit board, having a timing assembly, functions to determine the cycling frequency and duration of the relay contact operation. An integrated chip may be provided to provide protective safeguards for the circuit. A deflecting plate or buzzer may be incorporated to enhance the audible signal generated during cycling.
