How does a reed switch work
WebDec 2, 2024 · A reed switch is a sensor that uses an electromagnetic field to detect the presence or absence of a nearby object. The sensing element is a small, sealed tube containing two ferromagnetic metal reeds. When the distance between the reeds decreases, the magnetic force exerted on them increases, causing them to snap together and close … WebSep 1, 2016 · A switch can: act as an interrupter, interrupting the electric current. In the example in the figure below, the switch is either interrupting the current to flow and the LED doesn’t turn on, or it allows the electric flow and the LED turns on. act as a diverter, driving the current to other part of the circuit.

WebA reed switch is a type of electrical switch with a magnetic-based actuation method. It contains two or three thin and flexible metal wires or blades (i.e., reeds) that are either … WebAdditional important notes to bear in mind when understanding how a reed switch works: Any switch in an electric circuit operates a bit like a moveable bridge, where the current …
Reed switches come in two main varieties called normally open (normally switched off) and normally closed (normally switched on). The key to understanding how they work is to realize that they don't just work as an electrical bridge but as a magnetic one as well: magnetism flows through them as well as electricity. See more As you bring a magnet up to the reed switch, the entire switch effectively becomes a part of a "magnetic circuit" that includes the magnet … See more You can also get reed switches that work the opposite way: the two contacts are normally snapped together and when you bring a magnet up to the switch, spring apart. Reed switches … See more Another crucial thing I need to point out is that reed switches don't simply switch on when a magnet moves up close and off when it moves away (in the case of a normally open/off switch): they will typically switch on … See more The most common type of reed switch contains a pair of magnetizable, flexible, metal reeds whose end portions are separated by a small gap when the switch is open. The reeds are hermetically sealed within a tubular glass envelope. Another type of reed switch contains one flexible reed that moves between a fixed normally-open contact and a fixed normally-closed contact. The normall…
WebApr 21, 2024 · When the magnet moves closer to the switch, there is a gap between the reeds causing a higher reluctance, so it takes a larger field to magnetize the two reeds until they are attracted together. Once in contact, the reluctance is lower so the field strength to keep them magnetized is less than that required to pull them together.
WebDec 5, 2024 · Reed Switch Powering DC Motor This is a very effective way to protect the contacts of the reed switch, and it works well for inductive DC loads such as small motors.
