  • Publication number: 20240096566
    Abstract: A switch includes a housing and a metal terminal that is insert-molded into the housing. The metal terminal includes a contact portion provided on a first side of the metal terminal, an external connection portion provided on a second side of the metal terminal, and an embedded portion provided between the contact portion and the external connection portion and embedded in the housing. In the embedded portion, groove portions are formed in a front surface of the metal terminal and a rear surface of the metal terminal, the groove portions in the front surface being formed at positions different from the groove portions in the rear surface. The groove portions extend in a widthwise direction that is a direction intersecting an extending direction of the embedded portion.

  • Patent number: 11309143
    Abstract: A push switch including a pressing member, a movable contact, an interposed member, a first fixed contact, and a second fixed contact is provided. The pressing member includes a pressing portion configured to be pressed, and includes an elastically deformable peripheral wall portion having a lower end portion and extending downward and outward from the outer periphery of the pressing portion. The movable contact has a dome shape and is disposed below the pressing member. The interposed member is disposed between the pressing member and the movable contact, and is configured to press the movable contact by receiving and being pressed by the lower end portion of the peripheral wall portion of the pressing member. The lower end portion of the peripheral wall portion of the pressing member presses the interposed member while the peripheral wall portion is subjected to elastic deformation in response to the pressing portion being pressed.
