A transfer switch comprising a housing and a strip of metal enclosed in the housing, each end extending through the housing as a first connection. At least one first contact is integral to the metal strip. At least one second contact within the housing extends through the housing wall for a second electrical connection. At least one first section of the metal strip for severing and at least one second section of the metal strip having the properties of a hinge for pivoting. At least one exothermic source in the proximity of the first section that upon ignition severs the metal strip at the first section, and causes at least one segment of the severed metal strip to be propelled about the second section comprising the hinge, whereupon the first electrical contact is propelled to join the second electrical contact.
