It is not limited to the material of the conductive part 110, and it is possible to change various materials to enable the first terminal part 30 and the second terminal part 40 to be energized.

The elastic member 116 is constituted by a tension spring. One end of the elastic member 116 is fixed to the first tube 112 and the other end thereof is fixed to the second tube 114. 3, each stopper 117 is fixed to the fixing portion 115 formed inside each of the first and second tubular lamps, and thereby the first tubular tube 112 and the second tubular tube 114 have a stretchable structure.

The insulating housing part 120 includes a first insulating housing 122 formed to be hollow and a second insulating housing 124 slidably received in the first insulating housing 122 and a separator And a cover cap 125 covering the outer ends of the first insulative housing 122 and the second insulative housing 124, respectively.

The outer ends of the first tube 102 and the second tube 104 are connected to the cover cap 125. Accordingly, the first insulative housing 122 and the second insulative housing 124 are also expanded and contracted in conjunction with the expansion and contraction of the first tube 102 and the second tube.

The grounding part 130 is provided at both ends of the insulating housing part 120 and is connected to the conductive part 110 and grounded to the first and second terminal parts 30 and 40 of the cutout switch 10, respectively. The grounding unit 130 includes a first ground unit 140 coupled to one side of the cover cap 125 and connected to the conductive unit 110 and grounded to the first terminal unit 30, And a second ground unit 150 connected to the current-conducting unit 110 and grounded to the second terminal unit 40.
