Web16 de nov. de 2024 · When no magnetic field is present, the reed switch is open (the contacts are not touching). When a magnetic field is applied, the reed switch closes (the contacts touch), allowing current to flow through it. Reed switches can be used to detect the presence or absence of a magnetic field. WebTIDM-LC-WATERMTR. The operation of reed switches is as follows: The reed switch is opened when facing with a single north or south pole, but closed when facing the boundary of the poles (see Figure 4). Figure 4.

WebThe switching characteristics of a reed switch can also cause unintended double switching. Double switching is when the sensor output switches “ON” and “OFF” twice while the cylinder magnet passes the reed switch once. The false double switch of the sensor output is due to the non-uniform strength of a magnets force field. WebReed switches are a perfect trick for non-contact activation applications. We used a reed switch to detect when the doors of this TARDIS-themed music box opened. Or you can hook a large, door-specific reed switch …

WebFurthermore, reed relays can work in far more advanced ways. For example, an RF reed relay application is designed to switch high frequency signals.
