The pair of conductive strips in a casing rotatable between a first position and a second position relative to the pair of electrodes. The pair of conductive strips contacts the pair of electrodes when the casing in the first position. In a first embodiment, each electrode is a linear strip. Thus, the conductive strips disengage from the electrodes when the casing is in the second position. In a second embodiment, each electrode consists of a linear strip and at least one ear transversely projecting from the linear strip. Thus, the pair of conductive strips engages with the pair of linear strips of the electrodes when the casing is in the first position. The pair of conductive strips engages with the pair of ears when the casing is in the second position. ## Claims ### Claim 1 A socket terminal comprising: a shell comprising a base and a cover which is mounted on the base, wherein the base defines at least one pivot-receiving recess and wherein the cover defines at least one shaft-receiving hole; two electrodes which are mounted on the base and connected to a power supply; at least one socket member comprising: a casing comprising a pivot formed on a side and a disk-shaped shaft formed on an opposite side, whereby the pivot is received in the pivot-receiving recess and the disk-shaped shaft is received in the shaft-receiving hole, so that the casing is rotatable between a first position and a second position; and two conductive strips which are received in the casing so that they contact the electrodes when the casing is in the first position and that they do not contact the electrodes when the casing is in the second position. ### Claim 2 (depends on 1) A socket terminal in accordance with claim 1, wherein the base comprises a pair of grooves formed therein in order to receive the pair of electrodes. ### Claim 3 (depends on 1) A socket terminal in accordance with claim 1, wherein the base comprises a number of plastic locking protrusions formed thereon, and wherein the pair of electrodes comprises a number of holes formed therein, whereby the plastic locking protrusions are insertable through the holes and the tips thereof are heat pressed so as to form enlarged heads in order to restrain the pair of electrodes on the base. ### Claim 4 (depends on 1) A socket terminal in accordance with claim 1, wherein the casing comprises an annular flange formed about the disk-shaped shaft in order to keep the casing in the shell. ### Claim 5 (depends on 1) A socket terminal in accordance with claim 1, wherein the casing comprises two slots defined therethrough in order to receive the conductive strips. ### Claim 6 (depends on 5) A socket terminal in accordance with claim 5, wherein each conductive strip comprises a lead-contacting strip and an electrode-contacting strip projecting from the lead-contacting strip, the lead-contacting strips are inserted in the slots for contacting leads of electrical devices while the electrode-contacting strips are retained outsides the casing for contacting the electrodes. ### Claim 7 (depends on 6) A socket terminal in accordance with claim 6, wherein each lead-contacting strip comprises a press-out acting as a lead-contacting tab for firmly contacting the leads. ### Claim 8 (depends on 6) A socket terminal in accordance with claim 6, wherein each conductive strip comprises a press-out acting as a snapping member, the casing comprises a partition formed between the slots, and the partition comprises two snapping member-receiving recesses formed therein for receiving the snapping members when the conductive strips are inserted in the slots. ### Claim 9 (depends on 6) A socket terminal in accordance with claim 6, wherein each electrode-contacting strip comprises a contact and the each electrode comprises at least one contact, the contacts formed on the electrode-contacting strips engage with the contacts formed on the electrodes when the casing is in the first position. ### Claim 10 (depends on 1) A socket terminal in accordance with claim 1, wherein each electrodes comprises at least one ear transversely projecting therefrom for contacting the conductive strips. ### Claim 11 (depends on 10) A socket terminal in accordance with claim 10, wherein the pair of conductive strips contact the pair of ears when the casing is in the second position. ### Claim 12 (depends on 11) A socket terminal in accordance with claim 11, wherein each conductive strip comprises a lead-contacting strip and an electrode-contacting strip projecting from the lead-contacting strip, the lead-contacting strips are inserted in slots of the casing for contacting leads of an electrical device while the electrode-contacting strips are retained outsides the casing for contacting the electrodes. ### Claim 13 (depends on 12) A socket terminal in accordance with claim 12, wherein each electrode-contacting strip comprises a contact, each electrode comprises at least one contact, each ear comprises a contact, the contacts of the electrode-contacting engage with the contacts of the electrodes when they are in the first position, the contacts of the electrode-contacting engage with the ears when they are in the second position.
