The invention discloses a railroad track trip switch signal display device, which is provided with a base plate (4) horizontally suspending and stretching and fixed on the upper surface of a railroad track crosstie (12), a rotating shaft (2) is arranged on the suspending part of the base plate (4), the base plate (4) is penetrated by the rotating shaft (2) from above vertically down (4), and the rotating mechanism of the rotating shaft (2) is arranged under the base plate (4). With the technical proposal, the invention can send out correct visual signals to the switching operator, simple in structure and accurate in signals; the external height of the device is only one third of the vertical trip switch, effectively preventing trains from scraping and colliding with ground signaling apparatuses. Experiments prove that the invention has good effect and little malfunction, needing no special maintenance; demands for low cost and realizes high economic benefit, totally applicable to signal display of narrow tracks in small bounded area.
