Abstract: The pointer of an air-core meter instrumentation gauge comprises a driven hub via which the pointer is separably attached to a driving hub on the rotor of the air core meter movement. The driving hub is press-fitted to the rotor in proper circumferential alignment so that when the pointer is attached, the pointer will be inherently properly circumferentially oriented too. This is accomplished by providing a keyed connection between the driving and driven hubs such that the pointer can be assembled to the driving hub in only one particular circumferential orientation. The hubs also have a snap-together catch feature that is additional to the keyed connection.
