motor Air flow sensor (vent captor)

Do you know any supplier for air flow monitor (vent captor), used inside dc motors for cooling protection? It should be a small plate switching a contact when cooling air flows inside the motor. Thanks

Base on your location i think u need purchase from oversea,the nearest are Turkey,
