Abstract
A small-sized relay and a method for fabricating the same are disclosed. The relay comprises a prefabricated relay mechanism and an insulating cover covering the relay mechanism. Prior to assembling the relay mechanism and cover, a laser machining device is utilized to form, in the cover, holes of very small diameter which permit flow of gas molecules therethrough but do not permit the flow of dust particles or liquid molecules therethrough. The prefabricated relay mechanism is covered with the cover formed with such holes, and the opening of the cover except the portion including the holes is closed to hermetically seal the relay mechanism.
