Abstract
The present invention is provided with a contact switching mechanism having a movable contact member that is bent into a U shape, allowed to press and contact a fixed contact member side, and supported so as to freely tilt and move thereon. In this mechanism, a switching operation is carried out between contacts by reversing the movable contact member in a see-saw manner, with a tilt-movement fulcrum portion of the movable contact member being always in contact with the contact portion of the common fixed contact member. The movable contact member is allowed to have a spring function conformed to elastically shift in response to a switching operation in addition to a contact function that is inherent to the movable contact member so that it is possible to provide a switch having high reliability, such as a push-button switch and a rotary-lever switch, which can cut costs by reducing the number of parts, and ensure a superior contacting property.
