A cover member 30 having a bulged part 30a is formed of a material having rubber elasticity such as an elastomer and a silicone rubber. The cover member 30 is attached to the inside of the case 10 in such a manner that the bulged part 30a faces the opening 11 and at least the whole periphery of the opening 11 is fixed. To the rear face of the bulged part 30a of the cover member 30, a switch contact member 32 which can butt against the switch section 21 is fixed by two-color molding or sticking. |
