Abstract
An electrical switch with a conductive bridge, a first wire configured to provide continuity with the conductive bridge, and a biasing member connected to the first wire. The biasing member provides a threshold reaction force to maintain continuity between the first wire and the conductive bridge. The switch further includes a housing that directs tensile forces acting upon the first wire to oppose a reaction force of the biasing member. When a tensile force acting on the first wire exceeds a threshold reaction force of the biasing member continuity between the first wire and the conductive bridge is broken.
Claims20
An electrical switch for securing an article that opens under tension, comprising:
- a conductive bridge;
- a first wire and a second wire configured to be in continuity with the conductive bridge;
- a first biasing member configured to apply a reaction force to the first wire;
- a second biasing member configured to apply a reaction force to the second wire, wherein the first biasing member and second biasing member maintain continuity between the first wire and the conductive bridge and the second wire and the conductive bridge;
- and
- a housing that directs tensile forces acting upon the first wire or the second wire to act in opposition to at least one of the first biasing member and the second biasing member;
- wherein a tensile force exerted on either one of the first wire or the second wire that exceeds a threshold amount causes movement of either one of the first wire or the second wire with respect to the conductive bridge that breaks the continuity between the respective one of the first wire or the second wire and the conductive bridge.
An electrical switch for securing an article comprising:
- a conductive bridge;
- a first wire configured to provide continuity with the conductive bridge;
- a biasing member connected to the first wire, wherein the biasing member provides a threshold reaction force to maintain continuity between the first wire and the conductive bridge;
- and
- a housing that directs tensile forces acting upon the first wire to oppose a reaction force of the biasing member;
- wherein a tensile force acting on the first wire that exceeds a threshold reaction force of the biasing member causes movement of the first wire with respect to the conductive bridge that breaks the continuity between the first wire and the conductive bridge.
An electrical switch comprising:
- a conductive bridge;
- a first wire, wherein the first wire is coupled with and in continuity with a bullet, wherein the bullet is configured to slideably fit-within the conductive bridge to create a conductive path therebetween;
- a biasing member connected to the first wire, wherein the biasing member provides a threshold reaction force to maintain continuity between the first wire and the conductive bridge;
- and
- a housing that directs tensile forces acting upon the first wire to oppose a reaction force of the biasing member;
- wherein a tensile force acting on the first wire that exceeds a threshold reaction force of the biasing member breaks the continuity between the first wire and the conductive bridge.
