Reed Switch Polarity


-->

Reed Switch Polarity. With the magnetic field created by the coil, which must have the right polarity, the field is canceled and the magnetic circuit is interrupted, opening the reed switch contacts. The attractive polarity of the magnet magnetizes the reed.

Poles of opposite polarity are created and the contacts close when the magnetic force exceeds the spring force of the reed blades. At the center of the switch, the leads have opposite magnetic polarities and attract each other. The reed switch will remain in its closed state until another magnetic pulse with the opposite magnetic polarity is applied.

At the center of the switch, the leads have opposite magnetic polarities and attract each other. Reed switch operation happens when brought into proximity of a permanent magnet. The polarity and position of the magnet plays an important role in how your reed switch activates. At the center of the switch, the leads have opposite magnetic polarities and attract each other.
