1. A charging station for charging an electric vehicle, the electric vehicle including a charging interface on its roof, the charging interface including a landing zone with a seam extending along a direction of vehicle movement, comprising:
a charge head assembly arranged to overhang the roof of the electric vehicle;
a charge head movably attached to the charge head assembly, the charge head being configured to descend from the charge head assembly such that a bottom surface of the charge head contacts the landing zone of the charging interface on the roof of the electric vehicle; and
at least one head landing switch including a lever and a contact element, wherein a first end of the lever is rotatably coupled to a rotary switch on the charge head at a pivot point, and an opposite second end of the lever extends below the bottom surface of the charge head and is rotatably coupled to the contact element, wherein, when the charge head descends, the contact element contacts the landing zone before the bottom surface of the charge head contacts the landing zone, and causes the lever to rotate about the pivot point to move the contact element towards the bottom surface of the charge head and activate the rotary switch, and wherein a width of the contact element is greater than the width of the seam on the landing zone, and the contact element is configured to roll or slide on the landing zone across the seam.
