The invention discloses a high-sensitivity landing door switch. The high-sensitivity landing door switch comprises a controller, a switch body, a first triggering piece and a second triggering piece, a first displacement sensor and a second displacement sensor are arranged in the switch body, the switch body is fixed to an upper sill of an elevator, the first triggering piece and the second triggering piece are located on an active landing door and a passive landing door respectively, the first triggering piece directly faces the first displacement sensor, the second triggering piece directly faces the second displacement sensor, and the first displacement sensor and the second displacement sensor are electrically connected with the controller. The high-sensitivity landing door switch can recognize and judge the closing positions of the active landing door and the passive landing door, including the condition whether the active landing door and the passive landing door are closed or not and the distance between the active landing door and the passive landing door after the active landing door and the passive landing door are closed, so that the state of the landing door can be accurately judged in a high-sensitivity mode.
