Diagnostic tool for circuit interruption in pressure switches

A system comprising:

• a pressure switch comprising:
• a power circuit having a plurality of terminals and a corresponding plurality of contact members movable between an engaged position and an open position such that in the engaged position, the power circuit supplies a power to a pump;
• a portable diagnostic tool comprising:
• a tool body having at least one peripheral edge, a top face and a bottom face positioned on an opposite side of the tool body,
• a first hexagonal shape disposed within the tool body extending through the top face and the bottom face;
• a second hexagonal shape disposed within the tool body extending through the top face and the bottom face side, the second hexagonal shape is larger than the first hexagonal shape;
• and
• at least one leg extending from the at least one peripheral edge,
• wherein the at least one leg is configured to be inserted between the plurality of terminals and the plurality of contact members such that the plurality of contact members are held in the open position to interrupt the power supplied to the pump.

A method of interrupting a power supplied to a pump by pressure switch for diagnostic testing, the method comprising:

• removing, by a first hexagonal shape of a portable diagnostic tool, a nut of a housing cover to remove the housing cover from the pressure switch;
• moving a diaphragm plate of the pressure switch to move a plurality of contact members from a closed position to an open position creating a gap between the plurality of contact members and a plurality of terminals;
• inserting a leg of the portable diagnostic tool into the gap between a corresponding terminal member of the plurality of terminals and a corresponding contact member of the plurality of contact members such that the corresponding contact member of the plurality of contact members are prevented from making contact with the corresponding terminal member of the plurality of terminals and such that an abrasive surface of the legs cleans a carbon buildup on the each one the corresponding terminal member of the plurality of terminals;
• and
• performing a diagnostic test on the pump to determine at least one from a continuity of a pump wires, a resistance of the pump wires, and a ground of the pump wires.
