FLASHER SWITCH CIRCUIT INDEPENDENT OF POLARITY OF SUPPLY

摘要

A two pin switch for automobile direction signal flashers is wired so that the prongs of the switch may be plugged into the respective socket in either orientation, i.e, the switch is independent of polarity. The switch comprises a relay having a driven circuit to throw the relay on a signal of specific polarity. Both prongs are connected into both the driven circuit and diode bridges are provided to block transmission of negative signal to the driven positive terminal and to block transmission of positive signal to the driven negative terminal and to block transmission of signal other than that of the specific polarity to throw the relay.
