  • Reversible short-circuit and the use of said short-circuit in a photoelectric tube
    Patent number: 4987336
    Abstract: A reversible short circuit device in the form of a metal loop. The metal loop has a first base side which forms a first contact. Extending from the base side are second and third generally parallel sides. The second side includes a contact portion for engagement with an external object to provide an electrical connection therewith. The second and their sides are connected by a frangible fourth connection side. One of the second and third sides is subject to a recoiling force, which, when the connection side is interrupted or broken displaces the contact portion of the second side so as to reverse the short circuit. The short circuit device has particular application to photoelectric tubes to provide a means for interconnection of the tube components during manufacture, which may subsequently be reliably disconnected.
