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.

Description

technical field [0001] The present invention relates to a switch device having a fixed contact and a movable contact, and electronic equipment provided with the switch device. Background technique [0002] For switch devices used in input buttons and the like installed in various electronic devices such as notebook computers and mobile phones, for example, two fixed contacts arranged separately on the substrate and a metal dome serving as a movable contact are used. (Metal dome switch) is widely used (for example, refer to Patent Document 1). The switchgear using the metal arch piece conducts the conduction between the two fixed contacts through the elastic deformation of the metal arch piece due to the pressing operation. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-179921 [0004] However, in the switch device as described above, the metal arch piece elastically deforms and reverses when the switch is turned on, and the fixed contact collides with each ...
