Abstract: A single-pole magnetic reed relay includes a coil reel which has an axially extending reel portion, two opposite stop ends, a reed receiving groove extending axially in the reel portion and the stop ends, a reed entrance extending axially in the reel portion and the stop ends and communicated with the reed receiving groove in a radial direction, two extension portions formed outwardly of the stop ends, two first holes formed respectively and radially through the stop ends, and two second holes formed respectively and radially through the extension portions. The first and second holes are aligned axially with one another. Two coil terminals extend respectively through the first holes and have head portions positioned within the first holes. A reed contact unit is received in the reed receiving groove and has two conducting end portions which extend respectively through the second holes.
