Could a failing Handle Position Micro Switch cause the SHARK NAVIGATOR PET PRO (ZU62) to have symptom: Not Turning?

This momentary hinge-lever switch is located in the pivot neck of the floor nozzle and functions as an electromechanical interlock. It is designed to complete the circuit to the brushroll motor only when the handle is reclined; if the internal contact points fail or the hinge lever loses its tension, the brush motor will not receive the 120V signal required to engage.

// ENGINEER'S LOG

The Shark ZU62 utilizes a dedicated DC motor for the brushroll assembly, separate from the main vacuum suction motor. This motor is controlled via a series circuit that includes the main power switch (in position II) and a pivot-actuated micro switch. Forensic investigation typically shows that the brushroll 'Not Turning' is caused by a failure of this micro switch to close the circuit when the handle is lowered. This is a common pattern failure where mechanical vibration and frequent pivoting cause the switch terminals to lose continuity or the physical housing to shift, preventing engagement. Note that the brushroll is intentionally disabled in 'Hard Floor' mode (Position I) and when the vacuum is locked in the upright position.
