PROBLEM TO BE SOLVED: To provide a power switch low in a friction force at a slide portion and including an electrode capable of preventing a lubricant from being scattered.SOLUTION: In a power switch including a stator electrode 6 and a movable element electrode 2 disposed to face each other in a tank 1 sealed with insulation gas, each of the stator electrode 6 and the movable element electrode 2 has a contactor 4 energizing a movable conductor 8, and also has a slide material 12 on both sides of the contactor 4. The power switch includes a taper-shaped slide member 14 at an opening on a side facing the movable element electrode 2 in the stator electrode 6, and is provided with at least one groove 13, serving as a grease reservoir, between the contactor 4 and the slide material 12.SELECTED DRAWING: Figure 1 |
