PURPOSE:To improve the repetitive operating life and obtain a good contacting property during operation by constituting moving contacts with long and short wire sections connected mutually at their tips, and rotatably supporting the base end section of the long wire section on a fixed body. CONSTITUTION:When an operating lever 10 is rotated counterclockwise around a shaft body 12 to depress the tip section 5b of a moving contact 5, a short wire section 5A is displaced using its base end section 5a as a fulcrum, a long wire section 5B is rotated using its base end section 5c as a fulcrum, they are brought into contact with tip end sections 6a and 6b of fixed contacts 6A and 6B respectively, and contacts 6A and 6B are electrically closed. When the depressing action of the lever 10 is released, the contact 5 is returned to the free position. |
