The surface of the Switched Tray Drive is infinitely adjustable in height, pitch and proximity to the user and never touches the armrests. The installation of the switches, instead of requiring tedious mounting, are sandwiched between two layers of polycarbonate. The polycarbonate pieces are attached with a flat hinge and a single knob for fast, easy access to proximity switches.

This ground-breaking approach to tray driving also positions the display at midline for easy viewing and virtually eliminates exposed wiring. The Switched Tray Drive will reduce repair calls due to wiring damage and accidental disconnections and allow fast and easy field adjustments to switch positions. It can be operated with 4 or 5 naked proximity switches.
