Abstract
A charging cradle for a rechargeable medium having a charging contact. The charging cradle including a cradling-body, which includes a receiving area shaped to receive the rechargeable medium; a charging circuit having a charging and a non-charging state; a charging contact electrically coupled to the charging circuit and positioned to be alignable with the charging contact of the rechargeable medium; and a switch coupled to the cradling-body for interacting with the rechargeable medium to place the charging circuit in the charging state or the non-charging state. When the rechargeable medium is fully inserted into the receiving area such that the charging contact of the rechargeable medium is aligned with the charging contact of the cradling-body, the rechargeable medium, via the switch, places the charging circuit in the charging state, and when the rechargeable medium is not fully inserted, the switch places the charging circuit in the non-charging state to prevent short-circuiting of the charging circuit.
