- Insert the end of the Data Spring (B) wire at the large coil end, into the slot at the top of the Data Button (A). Twist the spring clockwise into the slot until the end of the wire at the small coil end lines up with the edge of the slot in the Button. 2. Place the Data Button (A) with the Data Spring (B), assembled, into the Contact Support (C). A B D The Contact (D) loop fits around the side o f the notch with the larger radii.
- Compress the Data Spring (B) into the center of the Data Button (A) and slide the Contact (D) onto the Contact Support (C). Check that the Data Button (A) is free to move up and down through the Contact (D). Slot in Button (A) to line up with notch in Contact Support (C). C End of wire to line up with notch in Contact Support XY XY
