Old telephones for the hook switch. c. 1960-1985
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.
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.
A reed relay is a type of relay that uses a reed switch enclosed in a glass tube for switching. It works by using a magnetic field to control the switching operation, allowing for high-speed and low-current switching in electrical circuits. Reed relays are commonly used in applications requiring compact size and low power consumption.
A simple machine.
The simple machine in a light switch is a "lever".
A reed switch uses two magnetized strips of metal to make or break a contact when a magnet is brought close to them. The door magnet near a reed switch on the door casing will cause the reed switch to close and moving the magnet away will cause the reed switch to open.
A clarinet reed.
It uses a double reed

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.

yes, the oboe uses a reed to produce sound.
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.
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.
The power switch is usually located on the side of the machine, and turns it off and on.
French Horn does not use a reed - it uses a funnel-shaped metal mouthiece.
