Abstract: The switch opening-closing mechanism, which makes it possible to increase a contact force so as to improve a vibration resistance, includes a sliding part, a second movable piece, and a second fixed contact. In a case where an amount of movement of a sliding part reaches a second retraction amount, the second movable piece comes into contact with the second fixed contact due to a spring force applied to the second movable piece. In a case where the amount of movement of the sliding part reaches a third retraction amount which is larger than a second retraction amount, the sliding part presses the second movable piece against the second fixed contact.

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.

Abstract: A switch includes a switching mechanism, an operating mechanism with a key which normally causes the switching mechanism to be in a switched-off condition when it is pulled out and to be displaced against a biasing force to be in a switched-on condition when the key is inserted, and a locking mechanism for maintaining the switching mechanism locked in the switched-on condition and releasing it from the locked condition if a load greater than a specified magnitude is applied to the key while the switching mechanism is locked such that the switching mechanism is set back in the switched-off condition. The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition.
