Cam Actuated Contact Patents (Class 200/551)
  • Patent number: 11309145
    Abstract: A switch device reduces an impact sound generated when the operation member returns to its original position. The switch device includes a housing member, an operation knob accommodated in the housing member and capable of being pushed, and a spring that urges the operation knob in a direction opposite to the pushing direction. The housing member includes a two-pronged stopper that regulates the movement of the operation knob in the opposite direction. The operation knob includes a tab that abuts on the two-pronged stopper. When the movement of the operation knob in the opposite direction is regulated, the two-pronged stopper and the tab make a line contact first.

  • Patent number: 7416319
    Abstract: The present invention relates to an illumination device for vanity mirrors of motor vehicle sun visors. The illumination device does not use cables as conducting elements nor external mechanical elements such as switches, simplifying the assembly operations. A conducting laminar element performs all of these functions: in addition to being the conducting means it acts as a switch for the device. This device is actuated by a cover that covers the mirror and is operated at the user's will. The device is characterised in that it is only illuminated in one position, in which the cover is not covering the mirror and the visor is in a shading position.

  • Patent number: 6005201
    Abstract: In a switch, the speed at which contacts are separated from each other is increased without depending on the speed at which an operating member is operated, so that an arc is prevented from being generated, to prevent the operating member to be deformed by heat generation and prevent the durability of the switch to be decreased due to the abrasion of the contacts. A movable contact member having movable contacts at both its ends is swingably supported with a common fixed contact projecting upward and serving as a fulcrum. A leaf spring is fixed to a slider. The leaf spring has a portion projecting in a U shape. The U-shaped portion is engaged with the center of the movable contact member. When the slider is moved, the U-shaped portion is distorted in the transverse direction. When the slider is further moved, the U-shaped portion gets beyond the fulcrum, so that the movable contact is rapidly separated from a normally open fixed contact.
