WebThe switching characteristics of a reed switch can also cause unintended double switching. Double switching is when the sensor output switches “ON” and “OFF” twice while the cylinder magnet passes the reed switch once. The false double switch of the sensor output is due to the non-uniform strength of a magnets force field. The whole thing is worked by a reed switch. Each cow's head is operated by a small electric motor that's connected to a circuit in which there's a normally open reed switch. The reed switch is positioned next to the train track and a little magnet is fitted to the side of the train.
