Operation of the control handle actuates six independently triggered SPDT (single pole, double throw) switches for signaling position status. A bank of 4-6 switches are triggered when the handle is moved from stowed position to down position or vice versa. The electrical signal initiate the deployment or retraction of the landing gear system.
A spring loaded center mechanism is designed to insure full handle travel to either stow or DN positions, while preventing an accidental stop in any other location in betvveen. An electrically operated down- lock prevents movement of the control handle to the stow position untl the aircraft becomes airborne.
The down-lock is operated by a continuous-duty rated solenoid.
A manual override permits emergency release of the handle lock.

The ergonomic, easy-to-use control knob is designed to meet the FAR Part 25 regulations.
Both the light plate and solenoid receive power through a MIL- DTL-38999 Series Ill connector.
The integrally moun1ed light plate design is manufactured in accordance with SAE 7788 Type VII.
The light plate provides the identification legends for the control handle Up and DN positions and for the down-lock release button.
