Describe the bug

When I use Switch with offBackgroundColor it throws TypeError: Cannot read property 'getTrackDrawable' of undefined error message.

<Switch [(ngModel)]="checklistFilters.visited" color="#b3e6f9" backgroundColor="#000000" offBackgroundColor="#444444" padding="0" margin="0" ></Switch>
