How Does a Reed Switch Works | Magnetic Sensor | Reed Switch Relay

A magnetic reed switch Sensor operates by the magnetic field. Like any other type of Electronic switch, a magnetic reed switch is used to control the flow of electricity. If the contact of a magnetic reed switching is open, electricity cannot Current flow. If the magnetic reed switch is closed, electricity can Current flow.

In most cases, the newer high-power magnets (Neodymium types) should have no trouble operating this reed sensor switch. Magnetic sensors have a working principle based on the measurement of changes in the magnetic moment of magnetic field material when exposed to magnetic fields.

The Form A magnetic reed switch has 2 contacts which are Normally Open (NO). Having NO contacts means that the introduction of a magnetic field will cause these contacts to close. That closure, in turn, also closes the circuit diagram, thereby conducting electricity.

It is a Reed Switch Sensor Module, In the presence of a magnetic field, a Reed Switch closes the circuit diagram. It's a type of passive electrical switching component that regulates the flow of electricity in a circuit.

Disadvantages: 1. Both spring switch contacts and reeds are very small and precise, not suitable for handling reed sensing switches caused by large voltages or large currents. Switches provide typical voltage and current ratings for switches.
