Abstract: A main switch with extended multiple individual conducting plates is provided, each switch comprises three conducting plates. A first conducting plate has a first fin extending into the main switch. A second conducting plate also comprises a second fin which extends into the main switch. The first and the second fins are positive terminals and are controlled by the corresponding switch to turn on and off. A third conducting plate has a third fin which is a negative terminal. Both the second and the third conducting plates comprise at least one clip extending outwardly to form conductors of a receptacle.

Abstract: A securing means for blades of an electrical plug, essentially comprised of a plug adapted with two resilient leaves in conjunction with a socket outlet, wherein, on both sides of the blade at its central portion is formed respectively an indent while at where appropriately relative to said gap on both sides to the front section of the resilient leave is separately made a protrusion bending outwardly, and the rear section of said resilient leaf is provided inside the plug; in another preferred embodiment, said two resilient leaves may be respectively embedded into sectional grooves on both sides of the blade; and furthermore in yet another preferred embodiment, a resilient covering leaf is formed as a protrusion at the corresponding to the plug gap respectively on both sides of the front section and a side leaf provided and connected to the rear section while the resilient covering leaf and the blade may be further riveted with a conductor from a plug adapter so that once the plug is inserted into the socket;

Abstract: A flat plug molding device comprised of a lower die, an upper die and a fixing seat in conjunction with conductor wire in practice, within, a cavity in proper thickness is provided and recessed at the center of the lower die, several holding ribs with arc top are provided on one side and a channel formed and recessed on the other side, with two penetrating holes provided at where appropriately in the center of said cavity, the upper die is provided in counter locked type, and a cavity is provided at the recess in the center of said upper die and a channel on one side corresponding to that at the lower die; the fixing seat are erected on it several protection walls at the right angle in proper height designed in conjunction with the route of the conductor wire and the shape of a conductor blade of the conductor wire, and two penetrating holes are provided at where appropriately; both ends of the conductor wire are each connected with a conductor blade which extends downward to form a plug blade with a hole; th
