An electronic apparatus comprises a case having a main surface and a side surface, and an operating member mounted on the side surface of the case for operating a switch function associated with the electronic apparatus. A substrate having a main surface and a side surface is disposed within the case. A printed wiring circuit is disposed on the main surface of the substrate. First and second conductive patterns are disposed in spaced relationship from each other on the side surfaces of the substrate and are connected to the printed wiring circuit. An elastic insulating member having first and second surfaces is disposed between the substrate and the operating member. A conducting element is fixedly attached to the first surface of the insulating member in facing and spaced apart relationship to the first and second conductive patterns. Upon depression of the operating member, the operating member contacts the second surface of the insulating member which undergoes flexure and moves the conducting element into contact with the first and second conductive patterns on the side surface of the substrate.
