It may be a phantom voltage, that you are seeing, many disposal units have a Allen key you can turn to make sure things are free if it turns + the reset on the disposal motor is set and the breaker is reset if it still won't start check the wiring at the switch. Disposals pull a large starting current and if back stabs were used it may have burned one of the stabs if you pull the switch out and it starts working get a new switch before it burns the wire off.
