How a Reed Switch Works

Ғылым және технология

The Reed Switch is the core element in Reed Sensors, Level Sensors and Reed Relays. A magnetic contact switch consisting of two ferromagnetic blades are hermetically sealed inside a glass tube. The glass tube is filled with a high purity inert gas. Under non operating conditions the reed switch contacts do not touch. MEDER electronic is leading the way in reed switch...

    This helped me so much in my physics exam for magnetism.

    Our reed switch blades use nickel/iron as the base metal and tungsten/rhodium sputtered on the contact area.

    Reed switches are definitely more susceptible to mechanical shocks. However, we have designed many standard and custom packages where the reed switch is potted into an assembly to help improve the shock resistance.

    thanks to Meder for explaining how important this is. for a solar system and a battery i would much rather trust a hermetic, materialist object, old-school style than a silicon switch which could potentially be destroyed by static or solar winds etc...

    @Zuja59 Hall sensors did not replace Reed. There are applications for both depending on a number of requirements. We have been manufacturing and designing reed switch and sensor products for over 25 years and new applications continue to arise, and even more so with miniaturization, low power and portable devices requirements. Please take a look at our Reed vs Hall Sensor comparison chart at meder.com in our Technical section under Technical Papers "Reed Sensors vs. Hall Effect Sensors"

    if you shake the Reed switch really hard is it gonna turn on without a magnetic field?

    weird. like eardrums sort of, only instead of sound vibrations, it's magnetic fields.

    Well, not really, unless you are talking about using them at a rapid speed. They don't vibrate or anything, that is just a magnet moving rapidly. Attach a screw to a magnet and you will see the screw is now also magnetic, but only when attached to the magnet. That is how these work, but at a distance. The metal is so delicate and the tube is at a high vacuum, so even the smallest of induced magnetism makes them stick together. Thankfully, the current induced when magnetized serves a secondary function of purging the induced magnetic field.

    The reed switches should not work. Suppose gap between the reeds is 10 micron. When a magnet is brought, the upper (or nearest reed will move by say15 micron. The lower reed being more distant, will move by 12 micron. So the resultant gap is 10+(15-12)=13 micron. I know there is a fallacy, but someone needs to explain in concrete terms.

    My interpretation is that you're not trying to attract both legs towards one side where you put a magnet. Instead, you're applying a magnetic field over both legs, turning both legs into magnets themselves. The legs then attract each other and close.

    I'm searching for an explanation of exactly how and why the magnetic field causes the reeds to move towards each other.
