The autopilot disconnect switch should be a normally open momentary switch for the G3X Touch Autopilot.
When momentarily depressed, the input on the servos is grounded and the autopilot is disconnected. If Control Wheel Steering is enabled, pressing and holding the switch will trigger CWS mode. For more information on Control Wheel Steering, see page 307 of the
G3X Touch Pilot's Guide, Rev. M.
