PROBLEM TO BE SOLVED: To provide a track short-circuit instrument which has a small number of components, is inexpensive, can visually confirm whether a track is short-circuited or not at the time of installation, and is prevented from being left behind at the time of recovery because the installed track short-circuit instrument emits light.SOLUTION: A track short-circuit instrument includes a first track contact member 1, a second track contact member 2 different from the first track contact member 1 and a short-circuit conductive cord 3 conducting the first track contact member and the second track contact member to each other, so as to connect right and left tracks via a short-circuit conductor cable having visibility and conducting the pair of contact members to each other for short-circuiting the right and left tracks.SELECTED DRAWING: Figure 1 |
