Abstract
A system includes a hearing device comprising a rechargeable power source, power management circuitry, and a first charging interface comprising a first cathode contact and a first anode contact spaced apart from the first cathode contact. A charging module comprises a second charging interface configured to detachably couple with the first charging interface of the hearing device. The second charging interface comprises a second anode contact having a contact surface and a displaceable second cathode contact. An arrangement is configured to displace at least a portion of the second cathode contact above the contact surface to facilitate electrical contact between the first and second cathode contacts prior to electrical contact between the first and second anode contacts. Charging circuitry of the charging module is coupled to the second charging interface and configured to charge the rechargeable power source of the hearing device.
