Claims

1. IN AN ARRANGEMENT FOR INDICATING ON A STATIONARY MEMBER THE POSITION OF AN ADJUSTING MECHANISM CARRIED BY A ROTATABLE MEMBER WITHOUT CONTACT BETWEEN THE STATIONARY AND ROTATABLE MEMBERS, THE COMBINATION OF A ROTATABLE MEMBER HAVING MEANS THEREOF FOR ESTABLISHING A MAGNETIC FIELD, AN ADJUSTING MECHANISM CARRIED BY SAID ROTATABLE MEMBER AND MOVABLE BETWEEN A PLURALITY OF OPERATING POSITIONS, A STATIONARY MEMBER HAVING MEANS THEREON RESPONSIVE TO SAID MAGNETIC FIELD, A SHIELD MOUNTED ON SAID ROTATABLE MEMBER AND MOVABLE BETWEEN A FIRST POSITION WHEREIN THE MAGNETIC FIELD BETWEEN SAID MAGNETIC MEANS AND SAID MAGNETIC RESPONSIVE MEANS IS UNDISTURBED AND A SECOND POSITION WHEREIN SAID MAGNETIC FIELD IS DISTURBED, AND MEANS ON SAID ROTATABLE MEMBER FOR MOVING SAID SHIELD TO ITS POSITIONS IN RESPONSE TO THE OPERATING POSITION OF SAID ADJUSTING MEMBER.
