<p>The adaptor includes an adaptor casing, a circuit board and a cover piece. The adaptor casing includes lower and upper casing halves which are made of plastic and which are coated entirely with a layer of conductive material. A circuit board is disposed in the adaptor casing and has a top surface provided with a switch unit that is aligned with an opening formed in the upper casing half and that extends out of the adaptor casing via the opening, a first edge provided with a first connector, and an opposite second edge provided with a second connector. Each of the first and second connectors has a support plate which closes a respective one of front and rear open ends of the adaptor casing. The support plates and the adaptor casing cooperatively form an enclosure for confining the circuit board therein. The cover piece is made of plastic and is coated entirely with a layer of conductive material. The cover piece is fitted detachably in the opening of the upper casing half.</p> |
