Abstract:
1. A socket switch for a light bulb comprising: a shell on which a through hole is formed for being penetrated through by an electric wire or a conduit that connects with the light bulb; and a main body screwed inside the shell, the main body comprising a grounding unit, a switch unit, an electric conduction unit, wherein the grounding unit comprises an elastic grounding sheet connected to the main body and an elastic metal grounding sheet flatly attached to a grounded position of the main body, the elastic grounding sheet being attached to the elastic metal grounding sheet and connected to the main body; the switch unit comprises a coupling means, an elastic switch sheet, and a switch means, the coupling means being pivotally connected to the switch means and connected to the main body, the elastic switch sheet being mounted on the main body and comprising a first electric conduction part and an elastic part, the first electric conduction part being connected to a positive electrode of the light bulb, the switch means being pivotally mounted between the coupling means and the main body, the switch means having a rotation shaft extending from the shell, a push part being mounted inside the switch means corresponding to the elastic part of the elastic switch sheet; and the electric conduction unit comprises an elastic electrode-touching sheet, an elastic electrode sheet, an insulator, and two partitions, the bottom of the elastic electrode-touching sheet being connected to a positive electrode of a power supply, the bottom of the elastic electrode sheet being connected to a negative electrode of the power supply, a second electric conduction part being mounted inside the elastic electrode sheet and connected to a negative electrode of the light bulb, the elastic electrode-touching sheet and the elastic electrode sheet being separated from each other, the elastic switch sheet being located on one side of the elastic electrode-touching sheet in a predetermined distance from the elastic electrode-touching sheet, whereby if the elastic part of the elastic switch sheet is pushed to touch the elastic electrode-touching sheet by the push part mounted inside the switch means, the positive electrode of the light bulb, which is connected to the elastic switch sheet, is electrically connected to the positive electrode of the power supply, which is connected to the elastic electrode-touching sheet, and the negative electrode of the power supply is electrically connected to the negative electrode of the light bulb via the elastic electrode sheet for lighting up the light bulb.
