Therefore, generally, the longer the exposed portion in the case 1 is, the lower the contact pressure at the free end should be. However, in the present embodiment, the length of the exposed portion of each of the fixed contact plates 9 to 12 is long regardless of the length. Is constant such that A = B. Therefore, in each of the fixed contact plates 9 to 12, a substantially constant and uniform contact pressure can be obtained.
