摘要： 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.

摘要： A highly durable, quiet switch includes a housing, a stationary contact terminal including a fixed portion, a moving contact terminal, a moving contact unit including a body, a moving portion, and an urging member and connected to the moving contact terminal, an operating unit, a first elastic unit that comes in contact with the moving contact unit and elastically deforms when the moving portion moves away from the fixed portion, and a second elastic unit including a contact point between the moving portion and the fixed portion facing the moving portion to come in contact with the moving portion. The second elastic unit elastically deforms and electrically connects the stationary and moving contact terminals when the moving portion moves toward the fixed portion and comes in contact with the contact point.
