Abstract
An electronic apparatus having a switch device capable of suppressing collision noise is disclosed. The switch device is equipped with a first fixed contact and a second fixed contact, and a metal dome that serves as a movable contact movable in a direction to be contacted with or separated from the first fixed contact. In a configuration in which the metal dome is moved to provide an electrical contact or a separation between the metal dome and the first fixed contact, whereby the first fixed contact and the second fixed contact are electrically connected therebetween, a conductive layer made of an anisotropic conductive sheet is provided between the first fixed contact and the metal dome.
Claims20
A switch device comprising:
- a first fixed contact separates from a second fixed contact;
- an anisotropic conductive sheet directly contacts said first and second fixed contacts, wherein said anisotropic conductive sheet is electrically conductive in only one of its three dimensions;
- and
- a movable contact to be moved to contact said anisotropic conductive sheet in order to provide electrical conduction between said first fixed contact and said second fixed contact, wherein said moveable contact has an outer peripheral edge portion electrically coupled on said first fixed contact.
An electronic apparatus comprising:
- a display chassis having a display device;
- and
- a body chassis having a keyboard and a touch pad, wherein said touch pad includes a switch device having
- a first fixed contact separates from a second fixed contact;
- an anisotropic conductive sheet directly contacts said first and second fixed contacts, wherein said anisotropic conductive sheet is electrically conductive in only one of its three dimensions;
- and
- a movable contact to be moved to contact said anisotropic conductive sheet in order to provide electrical conduction between said first fixed contact and said second fixed contact, wherein said moveable contact has an outer peripheral edge portion electrically coupled on said first fixed contact.
