Autopilot Disengage by KORRY. Master Caution illuminated button

Original Boeing style classic aircraft Autopilot Disengage Master Caution control button. Manufactured by KORRY.

The button would be found on alongside the MCP/Autopilot prominent to the upper glareshield. It will warn the pilot if/when the autopilot is disengaged.

The button illuminates (with power applied), and can be turned off by pressing. It has however NOT been tested, however the item is 'as removed' so is expected to work as intended.
