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 anisotropie conductive sheet is provided between the first fixed contact and the metal dome.
