Abstract
A casing for holding a key in one of two pivoted positions. The key pivots about an axis extending along one edge thereof when a lock is turned by the user of the key. An indicator may be attached to the key for extension through a small opening in the casing or housing when the key is in one position and for retraction below the level of the casing periphery when the key is in the opposite position. In a second embodiment, a portion of the casing may be pierced along three edges and arranged so that, when the key is in one position, the pierced portion is pushed above the casing periphery and, when the key is pivoted to the second position, the pierced portion is coextensive with or below the casing periphery. In a third embodiment, an indicator may be pivotally fastened in position between halves of the casing for movement (a) above and (b) even with or below the periphery of the casing when the key is pivoted.
