It will turn off if the north pole is applied to the face or the power is turned off.

Contactless bounce free hall effect technology provides precision control and long life operation. It was discovered by edwin hall in 1879. I decided to pursue a limit switch based upon a hall effect sensor and the following is what i learned along the way. The hardware setup for this experiment is identical to the limit switch demo except you only need one hall effect switch.

A hall effect switch will turn on in the presence of south magnetic field on its face or north magnetic field on the opposite side. The effect of generating a measurable voltage by using magnetic fields was discovered by dr. The heart of every micro switch hall effect de vice is the integrated circuit chip that contains the hall element and the signal conditioning electronics. For clarity the original effect is sometimes called the ordinary hall effect to distinguish it from other hall effects which have.

The hall effect is the production of a voltage difference the hall voltage across an electrical conductor transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.
