An apparatus includes an electrical assembly (e.g., a contactor) configured to be inserted into an enclosure. The electrical assembly includes at least one first contact configured to mate with at least one second contact disposed in an enclosure when the contactor assembly is inserted in the enclosure. The apparatus further includes an ejector mechanism including at least one pivoting member attached to the electrical assembly and configured to pivot about a point of attachment to the electrical assembly to apply a force to a surface of the enclosure and thereby cause movement of the electrical assembly within the enclosure. The movement of the electrical assembly caused by the ejector mechanism may disengage the at least one first contact from the at least one second contact. The electrical assembly may include a wheeled undercarriage and the at least one pivoting member may be attached to the undercarriage.
