Abstract
Abstract A small current switch comprises a pair of juxtaposed, resilient conductive wires each carrying a coiled reinforcement formed intermediate its ends. One end of each wire is secured to an insulating base. One of the wires has its other end extending in a straight form while the other end of the other wire is bent substantially at right angles so as to extend in a direction perpendicular to the one wire, the free end of which is mounted on a switching member. The switching member may be moved to bring the connected wire into and out of electrical contact with the other wire.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A small current switch comprising an electrically insulating base; a first resilient conductive wire having one of its ends secured to the base to provide a terminal for connection with an electrical circuit, the first wire being formed with a coiled reinforcement intermediate its ends and having its other end extending in a straight manner; a second resilient conductive wire having one of its ends secured to the base to provide another terminal for connection with an electrical circuit, the second wire being juxtaposed with the first wire and being formed with a coiled reinforcement intermediate its ends, the coiled reinforcement of the second wire being disposed in parallel relationship with that of the first wire, the other end of the second wire being bent substantially at right angles so as to extend in a direction perpendicular to the straight end of the first wire; and a switching member secured to the other end of the first wire for moving the first wire into and out of contact with the second wire.
Claim 2
Dependent Claim
172 words
A small current switch comprising an electrically insulating base; a first resilient conductive wire having one of its ends secured to the base to provide a terminal for connection with an electrical circuit, the first wire being formed with a coiled reinforcement intermediate its ends and having its other end extending in a straight manner; a second resilient conductive wire having one of its ends secured to the base to provide another terminal for connection with an electrical circuit, the second wire being juxtaposed with the first wire and being formed with a coiled reinforcement intermediate its ends, the coiled reinforcement of the second wire being disposed in parallel relationship with that of the first wire, the other end of the second wire being bent substantially at right angles so as to extend in a direction perpendicular to the straight end of the first wire; and a switching member secured to the other end of the first wire for moving the first wire into and out of contact with the second wire.
Claim 3
Dependent Claim
63 words
The switch of claim 1, wherein the ends of said wires secured to said base are arranged in said base so that the free ends are displaced from one another when the switching member is in a first position and said free ends are engaged when the switching member is moved in a first direction against the resilience of the wire secured thereto.
Claim 4
Dependent Claim
62 words
The switch of claim 1, wherein the free ends of said wires secured to said base are arranged in said base so that the free ends engage one another when the switching member is in a first position and said free ends are disengaged when the switching member is moved in a first direction against the resilience of the wire secured thereto.
