Abstract:
Disclosed is a relay. The relay comprises: a coil; an iron core, the coil being provided outside the iron core; a transmission shaft, wherein a lower end of the transmission shaft is connected to the iron core; first and second binding posts; a moving contact board, wherein the moving contact board is provided at an upper end of the transmission shaft, the moving contact board can be driven by the transmission shaft to move between a first position and a second position, the first and second binding posts are conducting when the moving contact board is at the first position, and an electric connection of the first and second binding posts is disconnected when the moving contact board leaves the first position; a permanent magnet, the permanent magnet being provided on the moving contact board; and a magnetically sensitive switch, wherein the magnetically sensitive switch is located at one side of the permanent magnet, the magnetically sensitive switch is switched from a first state to a second state in the process of the permanent magnet moving from down to up, and the magnetically sensitive switch is switched from the second state to the first state in the process of the permanent magnet moving from up to down.
