摘要： PURPOSE:To enable a replacement of a connected line to be attained simply without decomposing a rail or the like by a method wherein an auxiliary rail and a rail are provided electrodes in a direction perpendicular to each of the rail surfaces, these electrodes are extended out of structure of insulation material as well as rails and then connection lines operated as an opened switch are fixed. CONSTITUTION:An auxiliary rail 12 having a T-shaped electrode is inserted into a rail 13 having two T-shaped electrodes with an insulation material 9 being held therein. The auxiliary rail and the rail are fastened together with a pressing member 11 and a spacer 10 of insulating material and fixed. To the extreme end of the electrode is fixed a connection line 8 composed of a metallic foil for connecting between the auxiliary rail 12 and the rail 13. Since the electrode fixed to the auxiliary rail and the rail is of a reciprocating type, an inductance of this circuit is low. A part of the connection line 8 melted to act as an opened switch is placed out of the rail structure, it may easily be replaced without decomposing the rail structure.
