Brentek Reed DRY-type Dry Contact Modules can control both large and small signals they can eliminate the need for specifying and stocking separate AC and DC module types. The reed switch is an electrical switch operated by an applied magnetic field.It was invented in 1922 by a professor at Leningrad Electrotechnical University, and later evolved at Bell Telephone Laboratories in 1936 by Walter B. Ellwood into the reed relay. Reed relays and reed switches are used in many areas where smaller, faster acting relays are needed in an electronic or electrical circuit. The magnet found inside the reed relays creates magnetic field that help in the switching of circuits. Drill/Router Bits. Dry Reed Relays Dry reed relays are also operated by energizing a coil, but in this type of relay, the coil is wound around the switch so that the induced magnetic field closes the switch. Types of Relays¶ Although there are more than a dozen relays in our website, in general, there are only three types: Electromechanical Relay, Solid State Relay and Reed Relay. The Grove-Dry-Reed Relay is a relay module which works through magnetizing the vibration reed via the current in the coils. Compared to electromagnetic relays, the contacts completely sealed is the biggest feature of the Dry-Reed Relay. A relatively small current is used to create a magnetic field in a coil within a magnetic core and this is used to operate a switch that can control a much larger current.
