Patent Issued for Thin Profile Cam Switch Assemblies

May 7, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Apple Inc. (Cupertino, CA) has been issued patent number 8704119, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventor is Pletenetskyy, Andriy (Sunnyvale, CA).

This patent was filed on April 11, 2012 and was published online on April 22, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Electronic devices may include several types of input components that can be used by a user for providing instructions or commands to the electronic device. For example, the input component may be a switch assembly including a button that may be moved to one of at least two different positions. The button may be aligned with a slider that can slide along a linear track. Consequently, as the button is moved from one position to another, the movement of the button causes the slider to slide along the track. A switch box can be coupled to the slider via an engagement member that can detect mechanical movement of the slider and translate this movement into electrical signals. These electrical signals can then be interpreted by other components of an electronic device in order to alter a functional state of the device.

"Given the trend to incorporate more features into devices, while simultaneously maintaining or shrinking the physical dimensions of the device, other components such as switch assemblies within the device may need to shrink. Accordingly, switch assemblies constructed with a thin operational profile are needed."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventor's summary information for this patent: "Rotational switch assemblies having a thin operational profile are provided for use in electronic devices. Rotational switch assemblies in accordance with embodiments of the invention can include a button, an engagement member, and switch housing. The switch housing includes a radial spring, a post, and at least two contact spring arms. The engagement member includes at least two contact pads and at least two position notches and is mounted to and operable to rotate about the post to one of at least two positions. When the button is moved from one position to another, this movement is translated to the engagement member, which rotates from one position to another, and as the engagement member rotates, the radial spring engages the position notch corresponding to the position of the engagement member, and one of the contact pads engages a corresponding one of the contact spring members for that position."
