Reed switch (magnetic button) Y213

Reed switch is a sealed contact, which begins to pass an electric current when exposed to a magnetic field. There are different types of reed switches, but we will consider the most common, with normally open contacts, which will close with the appearance of a magnetic field. Reed switches made in China Y213 have acceptable characteristics and refers to an extremely low price.

In the photo you see the device of this device: a glass flask filled with an inert gas, a flask with two movable elastic contacts, which easily connect when a magnet is brought up.
