What is a reed switch used for?

How electromagnet works on reed switch?

When an electromagnet is turned on, it generates a magnetic field that attracts the metal reed in the reed switch, causing the switch contacts to close. When the electromagnet is turned off, the magnetic field disappears and the contacts open again. This allows the reed switch to act as a sensor or control device in various applications.


How does metal corrosion affect a reed switch?

Metal corrosion can lead to the formation of insulating layers on the metal contacts of a reed switch, preventing proper electrical contact. This can result in unreliable switching behavior or complete failure of the reed switch. Regular maintenance and protection from corrosive environments can help prolong the lifespan of a reed switch.


Does a key or reed switch have a symbol which could be put in a circuit diagram?

Yes, both a key switch and a reed switch have standard symbols that can be used in circuit diagrams. The symbol for a key switch is typically represented as a rectangle with a gap in the top portion, symbolizing the key inserted. The symbol for a reed switch is often depicted as a rectangle with two parallel lines inside to represent the reed contacts.

It can, but it should not. If it does, then the reed-switch is defective ... its contacts have most likely deteriorated on account of excessive current at some time.


Why does more current flow through copper wire than a reed switch?

Ideally the reed switch should be able pass as much current as the wire supplying it. A voltage drop across the switch would indicate resistance and suggest that the maximum rated current has been exceeded. Reed switches are delicate and should only switch small currents. They are used where actuation by a magnet is required, without mechanical interference. To switch larger currents a relay should be used, fed from the reed.
