Then, the principle of the removal to foreign matter describes.First, to producing and have the situation of foreign matter to describe on the inclined-plane 6b of the protuberance 6 at fixed contact 2.The foreign matter producing on the inclined-plane of protuberance 6 6b easily moves to the bottom 6c of protuberance 6 along the inclined-plane 6b of protuberance 6.And, the first opposed faces 2a of fixed contact 2 becomes the convex surface of the mode bending of protruding with (Z1 direction) upward, and the foreign matter therefore moving to the bottom 6c of protuberance 6 easily moves to the direction of the peripheral part 3e of the first opposed faces 2a along the first opposed faces 2a.Therefore, utilize and be accompanied by fixed contact 2 and the contact of travelling contact 3 or the vibration separating, foreign matter is moved to the outside of the first opposed faces 2a via the first opposed faces 2a from the inclined-plane 6b of protuberance 6, it can be removed from contact point structure 1.Produce and have foreign matter at the bottom 6c of the protuberance 6 of fixed contact 2, utilize the structure of above-mentioned the first opposed faces 2a, foreign matter is moved to the outside of the first opposed faces 2a via the first opposed faces 2a from the bottom 6c of protuberance 6, it can be removed from contact point structure 1.
Then, to producing and have the situation of foreign matter to describe between the protuberance 6 at fixed contact 2 and the slot part 9 of travelling contact 3.The second opposed faces 3a place at travelling contact 3 forms slot part 9, in the time that fixed contact 2 contacts with travelling contact 3, between the upper end of protuberance 6 6a and the upper end 9a of slot part 9, occurs the first gap 13.Therefore, even if produce foreign matter between the upper end of protuberance 6 6a and the upper end 9a of slot part 9, can not be accompanied by the contact of fixed contact 2 and travelling contact 3 or separate and crush foreign matter, and can make foreign matter move by the first gap 13 along the extending direction of slot part 9 yet.Therefore, to foreign matter, effect is accompanied by fixed contact 2 and the contact of travelling contact 3 or the vibration separating, make foreign matter move on backward the first opposed faces 2a and fall along the extending direction of slot part 9, can make it move to the outside of the first opposed faces 2a from the first opposed faces 2a.Foreign matter can be removed from contact point structure 1 like this.
In such contact point structure 1, for example, configuring in the mode that (Y1-Y2) direction is extended only forwards, backwards at whole slot part 9, (Y1-Y2) direction before and after the direction that foreign matter is moved from the upper end 6a of protuberance 6 is defined as.Therefore,, in the time supplying with foreign matter to slot part 9 one by one from multiple protuberances 6, the removal of foreign matter cannot be able to catch up with the supply of foreign matter, easily makes slot part 9 stop up.But, in the present embodiment, slot part 9 by first slot part 10 of linearly extension in the direction of front and back (Y1-Y2) and in the direction of left and right (X1-X2) five the second slot parts 11 of linearly extension form, can make the foreign matter producing at nine protuberances, 6 places in front and back (Y1-Y2) direction and left and right (X1-X2) direction, disperse movement.Therefore, can prevent that the movement of foreign matter from concentrating in one direction, thereby can suppress the obstruction of slot part 9.
In addition, in the present embodiment, slot part 9 extends to the peripheral part 3e of the second opposed faces 3a of travelling contact 3, even if therefore supply with one by one foreign matter to slot part 9, also can easily discharge towards the outside of the second opposed faces 3a from peripheral part 3e side.Therefore, can further suppress the obstruction of slot part 9.
In addition, in the present embodiment, the first slot part 10 and central the second slot part 11C are all opposed with central spud 7, and orthogonal in the centre of the second opposed faces 3a.Therefore, utilize the first slot part 10 and central the second slot part 11C, can make foreign matter (Y1-Y2) direction and left and right (X1-X2) the direction dispersion movement forwards, backwards producing at central spud 7 places.And, even if supply with one by one foreign matter from central spud 7 to slot part 9, also can suppress the obstruction of slot part 9.
Then, the situation that is attached with foreign matter on the inclined-plane 6b of the protuberance 6 at fixed contact 2 is described.In the present embodiment, five the second slot parts 11 in slot part 9 extend to the direction parallel with rotation axis 5.And, in the time of operation, by travelling contact 3 is rotated centered by rotation axis 5, fixed contact 2 is contacted with travelling contact 3.Therefore,, in the time of operation, the second slot part 11 (slot part 9) contacts with protuberance 6 in the top from protuberance 6 (Z1 direction) roundabout mode.And the bottom 9c of the second slot part 11 (slot part 9) arranges and contacts with the inclined-plane 6b of protuberance 6 to wipe the mode of rubbing with the inclined-plane 6b of protuberance 6.In the case of being attached with foreign matter with the inclined-plane 6b of the opposed protuberance 6 of the second slot part 11, can utilize the action of such the second slot part 11 (slot part 9) and the inclined-plane 6b from protuberance 6 wipes by it.
