Discharging the Electrostatic Potential of a Keyboard Operator Through the Spacebar

Disclosed are methods for discharging a keyboard operator by contact with a spacebar which is molded of a conductive plastic. This is a high usage key, which insures that most operators will contact it frequently.

In Fig. 1, the path to ground is through the spacebar 1, a ground clip 2 attached to the spacebar, and a ground wire 3 running from the ground clip 2 to the keyboard baseplate 4. The keyboard baseplate 4 is connected to the system ground.

In Fig. 2, the path to ground is through the spacebar 1, the stabilizer bail 2, the ground strap 3, and the keyboard baseplate 4. The unique aspect of this design is the use of the stabilizer bail in the ground path. This allows the spacebar to be removed and reinstalled without removing and reinstalling any ground wires.
