An electrical switch includes a tubular housing that includes an interface positioned intermediate the conductor receiving end and the operating end. An operating rod extends through the housing. A fixed contact is electrically coupled to the operating end. A moveable contact is electrically coupled to the interface and the operating rod, wherein the moveable contact is moveable between a first position contacting the fixed contact and a second position separated from the fixed contact. A diaphragm is positioned in the tubular housing between the interface and the operating end and includes a first tubular portion and a second tubular portion. Movement of the operating rod from the first position to the second position causes the second tubular portion to move relative to the first tubular portion, thus deforming the shoulder portion.
