IPC: H01R4/58
Filed: 2001-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a movable contact blade structure of a switch, capable of miniaturizing a movable contact blade and an internal member such as a switching mechanism or the like and miniaturizing the entire switch as well. SOLUTION: When the thickness of the base end part of a movable contact blade 17a, 17b is expressed by L1, the thickness of a current carrying part 21 is expressed by L2, and the thickness of an arc resistant metal 22 is expressed by L3, the movable contact blade 17a, 17b is formed so that L1>L2>L3 is satisfied. Also, a heat capacity reducing as the length of the movable blade 17a, 17b is shortened is compensated by thinning the thickness of the tip side of the movable contact blade 17a, 17b and thickening the thickness of the base end side. Thereby, the length of the movable blade 17a, 17b can be shortened with the sufficient heat capacity secured. The driving torque of the movable contact blade 17a, 17b gets small as the thickness of the tip side of the movable blade 17a, 17b reduces. Therefore, the driving force of a switching mechanism is reduced, and the switching mechanism part can be miniaturized as a result.
