<P>PROBLEM TO BE SOLVED: To provide a contact point switching device that can prevent deposition between a fixed contact point and a movable contact point and can reduce contact resistance upon closing. <P>SOLUTION: A case 1 has a storage room 10 in which a movable contact point 5 formed of first conduction liquid is stored, a first channel 11 for making the movable contact point 5 displaceable, and plural second channels 12 and a third channel 13 which are branched from the first channel 11 and intercommunicate with the first channel 11 at distant positions from one another in the extension direction of the first channel 11. Second conduction liquid 7, 7, 7 which is contacted with and conducted to each of first contact terminal portions 61a, 61b and a second contact terminal portion 62 and which the movable contact point 5 approaches and gets away from is accommodated in each of the second channels 12, 12 and the third channel 13. The fixed contact point 6 containing the plural first contact point terminal portions 61a, 61b, the second contact point terminal portion 62 and each second conduction liquid 7, 7, 7 and the movable contact point 5 approach and get away from each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
