Disclosed is a cable lock particularly configured for securing the cover of a control switch, such as a fluid flow or pressure switch used in industrial pressurized air and water delivery systems that include a fluid line tap, a base, a flow or pressure switch mounted on the base, and a switch cover removably attached to the base and covering the switch. The cable lock is specially configured with a first loop portion that wraps around the fluid line tap, and a second loop portion attached to the first loop portion and positioned at approximately 90° to the first loop portion that wraps around the switch cover so as to prevent unauthorized removal of the cover and unauthorized access to the switch.

1. A switch cable lock system comprising: a switch cover having a top surface, two end walls, two side walls, and a rectangular rim extending around a bottom edge of said two end walls and said two side walls, and fasteners for affixing said switch cover over a switch; anda cable lock comprising: a first, one-piece, unitary loop portion having a first loop first end, a first loop second end, and a midpoint between said first loop first end and said first loop second end, said first loop portion defining a longitudinal axis extending through said first loop portion, and a lock affixed to said first loop second end, said lock having a lock body extending from said first loop second end and along said longitudinal axis, and said lock body having a receiver mounted in a sidewall of said lock body and extending in a direction perpendicular to said longitudinal axis;a second, one-piece, unitary loop portion permanently affixed to the first loop portion and situated at a 90° angle to said first loop portion, said second loop portion having a second loop first end attached to said first loop portion at a point between said midpoint and said first loop first end, and said second loop portion having a second loop second end attached to said first loop portion at a point between said midpoint and said first loop second end, wherein said second loop portion is sized to extend over and to be in contact with said switch cover top surface and said switch cover side walls when said first loop portion is closed and positioned below said rectangular rim; anda lock head affixed to said first loop first end and extending outward from said first loop first end along said longitudinal axis, wherein said lock head is insertable into said receiver so as to lock said first loop first end in a position that is at 90° to said first loop second end. 2. The switch cable lock of claim 1, wherein said first loop portion is sized to extend around a fluid line tap head of a flow or pressure switch to which said switch cover is attached when said lock head engages said receiver. 3. The switch cable lock of claim 1, wherein said second loop portion is further sized to extend around said side walls and said top surface of said switch cover while positioning said first loop portion immediately adjacent a base of a switch to which said switch cover is attached. 4. A method of locking a cover of a switch to a base of a switch, comprising the steps of: providing a switch cover having a top surface, two end walls, two side walls, and a rectangular rim extending around a bottom edge of said two end walls and said two side walls, and fasteners for affixing said switch cover over a switch, and attaching said switch cover over a fluid line tap head of a flow or pressure switch;providing a switch cable lock comprising: a first, one-piece, unitary loop portion having a first loop first end, a first loop second end, and a midpoint between said first loop first end and said first loop second end, said first loop portion defining a longitudinal axis extending through said first loop portion, and a lock affixed to said first loop second end, said lock having a lock body extending from said first loop second end and along said longitudinal axis, and said lock body having a receiver mounted in a sidewall of said lock body and extending in a direction perpendicular to said longitudinal axis;a second, one-piece, unitary loop portion permanently affixed to the first loop portion and situated at a 90° angle to said first loop portion, said second loop portion having a second loop first end attached to said first loop portion at a point between said midpoint and said first loop first end, and said second loop portion having a second loop second end attached to said first loop portion at a point between said midpoint and said first loop second end, wherein said second loop portion is sized to extend over and to be in contact with said switch cover top surface and said switch cover side walls when said first loop portion is closed and positioned below said rectangular rim; anda lock head affixed to said first loop first end and extending outward from said first loop first end along said longitudinal axis, wherein said lock head is insertable into said receiver so as to lock said first loop first end in a position that is at 90° to said first loop second end;positioning said second loop portion around said switch cover of said flow or pressure switch, such that said second loop portion extends across said top surface and said two side walls of said switch cover;wrapping said first loop portion around said fluid line tap head of said flow or pressure switch; andlocking said first loop portion around said fluid line tap head so that said first loop portion is immediately adjacent a base of said flow or pressure switch. 5. The method of claim 4, wherein said first loop portion is sized to extend around said fluid line tap head when said lock head engages said receiver. 6. The method of claim 4, wherein said second loop portion is further sized to extend around said side walls and said top surface of said switch cover while positioning said first loop portion immediately adjacent said base of said flow or pressure switch.
