Abstract: An electromagnetic switch including a first stationary electric contact, a second stationary electric contact, a mechanical contact, and a moveable contact. The electromagnetic switch is configured for reciprocal motion of the moveable contact into and out of contact with the first stationary electric contact and the second stationary electric contact, wherein the moveable contact remains in contact with the mechanical contact (e.g., a non-conducting contact) throughout the reciprocal motion. In various embodiments, the moveable contact is configured so that at the end of the reciprocal motion three contact points occur, and a triangle defined by the three contact points encloses a center of force of the reciprocal motion.

Abstract: An integration assembly for a battery pack mounted between the passenger cabin floor panel of an electric vehicle and the driving surface is provided, the assembly utilizing a multi-layer thermal barrier interposed between the battery pack enclosure and the passenger cabin floor panel, where the multi-layer thermal barrier provides noise isolation, thermal isolation and vibration damping, and where the multi-layer thermal barrier is compressed when the battery pack enclosure is mounted to the vehicle. The multi-layer thermal barrier is comprised of a first layer formed from a compressible and conformable elastic material and a second layer formed from a conformable thermally insulating material. The multi-layer thermal barrier may also include a moisture barrier layer that encases the first and second layers, for example a moisture barrier layer fabricated from a plastic. A sealant may be used to seal and bond the moisture barrier layer to the battery pack enclosure.
