A relay consisting of an energizing coil and a metallic reed switch mechanism. the reeds serve as both core and contacts, which are not hinged or pivoted and which move by flexure when acted upon by a magnetic field induced by energization of the coil. it may also include a biasing magnet. the biasing magnet, either aids or opposes the movement of the reeds and the opening or closing of the contacts. for items in which actuation is dependent on the resonant frequency of the reeds see relay, resonant reed. excludes relay, electromagnetic.
