    摘要: A collapsible link device includes a side frame, a carrier, a main contact arm, a plurality of collapsible links, and a release mechanism. The carrier is pivotably coupled to the side frame. The main contact arm is pivotably coupled to the carrier and includes a first end including a first electrical contact. The plurality of collapsible links are pivotably coupled to the side frame and the carrier. The release mechanism is pivotably coupled to at least one of the collapsible links and the carrier. The plurality of collapsible links are movable between an uncollapsed position in which the first electrical contact contacts a second electrical contact and a collapsed position that results from the first electrical contact separating from the second electrical contact.
