terminal spring. Strip any insulation from the wire to give 7 to 9 mm bare wire.
Push the wire into the opening, and, while holding it in position, withdraw the
screwdriver to release the spring. The wire will now be firmly held in place.
See Figure 4, below.

bare ends together before insertion. NOTE
