DEAD KEY DISCONNECT MECHANISM THEORY
The purpose of the dead key disconnect is to inhibit the dead key mechanism and allow normal escapement for dead key positions. This is done with a cable which pivots the dead key cable away from the finger on the dead key bail. The disconnect cable is controlled from the keyboard by a wheel mounted next to the tab set and clear keybutton.
With the control wheel rotated away from the operator, the dead key mechanism operates normally. With the control wheel rotated toward the operator, the dead key mechanism is disconnected and escapement occurs for dead key positions (Figure 1).
