Abstract
The switch structure according to the present invention is obtained by interposing an elastic connection member between the circuit board provided with electrodes and a push switch fixed to a case of an electronic device. The elastic connection member has a structure in which conductive layers and insulation layers are alternately laminated. The conductive layers of a first lamination layer surface on which the conductive layers and the insulation layers of the elastic connection member are exposed abut against the electrodes so that the electric connections therebetween are established. The push switch is pushed down, and a contact portion thereof abuts against the plurality of conductive layers on a second lamination layer surface, whereby the electrodes are in a conductive state. Even if the push switch is pushed strongly, the elastic connection member deforms to absorb the force. As a result, the switch structure which hardly breaks is obtained.
