1. A refrigerator appliance comprising: a cabinet having a temperature-controlled compartment defined therein;a shelf ladder disposed in the temperature-controlled compartment and providing a plurality of shelf mounting positions;an electrical connector corresponding to each of the plurality of shelf mounting positions, wherein each of the electrical connectors comprises an actuator movable from a first position to a second position and an electrical contact configured to automatically move from a disengaged position to an engaged position in response to the actuator moving from the first position to the second position; andan adjustable shelf removably mountable in one of the plurality of shelf mounting positions such that the actuator of the corresponding electrical connector is held in the second position by a weight of the adjustable shelf and the electrical contact of the corresponding electrical connector engages the adjustable shelfwherein each of the electrical connectors further comprises a resilient member that biases the actuator toward the first position, the resilient member being deformable by the weight of the adjustable shelf. 2. The refrigerator appliance of claim 1, wherein the adjustable shelf comprises a mounting bracket configured to be cantilevered on the shelf ladder, the mounting bracket including a tab configured to extend through a slot formed in the shelf ladder to engage the corresponding electrical connector. 3. The refrigerator appliance of claim 2, wherein a first surface of the tab that is configured to engage the actuator of the corresponding electrical connector and a second surface of the tab that is configured to interface with the electrical contact of the corresponding electrical connector are perpendicular to one another. 4. The refrigerator appliance of claim 2, wherein each of the electrical connectors further comprises an additional electrical contact configured to automatically move from the disengaged position to the engaged position in response to the actuator moving from the first position to the second position, the electrical contact and the additional electrical contact configured to supply power at different current levels. 5. The refrigerator appliance of claim 4, wherein the tab of the mounting bracket includes at least two conductors configured to interface with the electrical contact and the additional electrical contact of the corresponding electrical connector.
