Let's take a closer look at how they work! Photo: A typical reed switch (a Comus RI-23). You can just see the two overlapping metal contacts (reeds) inside the glass envelope. The contacts spring together and touch when the switch is "on"; they spring apart and interrupt the circuit when the switch is "off." What problem do reed switches solve?
How is rotary motion used to actuate a reed switch?Rotary motion may also be used to actuate a reed switch, In A and B the switches are stationary and the magnets rotate. In examples C and D both the switches and the magnets are stationary and the switch operates whenever the cutout portion of the magnetic shield is between magnet and switch.
How many volts can a reed switch Switch?Reed switches with a vacuum inside the glass envelope can switch thousands of volts. Reed switches can be used to directly switch a variety of loads ranging from nanovolts to kilovolts, femtoamperes to amperes, and DC to radio frequency.
Is a reed switch nonferromagnetic?The normally-closed contact is non-ferromagnetic and is closed by the flexible reed's spring force. Although reed switches with multiple poles are possible, more often an assembly of single-pole reed switches is used for multi-pole applications.
