Terminal connector securing wire with a wide range of diameters to a conductor of an electric power switch and an electric power switch incorporating the terminal connector

An electric power switch comprising:

• a molded casing with an upper face, a lower face and an end face extending between the upper face and the lower face and an elongated recess in the end face;
• a switch conductor projecting from the molded case into the elongated recess;
• and
• a reversible terminal connector for securing a wire to the switch conductor in the elongated recess and comprising a collar having a slot extending laterally and sized for receiving the switch conductor, an aperture extending laterally in the collar adjacent to and intersecting the slot, the slot being adjacent a first end of the collar and the aperture being adjacent a second end of the collar, the collar having a first longitudinal hole extending from the first end to the slot and a second longitudinal tapped hole extending from the second end of the collar to the aperture, a fastener extending through the first longitudinal hole engaging the switch conductor to clamp the collar to the switch conductor and a second fastener in the form of a screw which threads into the second longitudinal hole and clamps the wire inserted into the aperture against the switch conductor to effect an electrical connection between the wire and the switch conductor, the collar and the elongated recess being shaped such that the collar can be reversibly clamped to the switch conductor with the second fastener selectively accessible through the elongated recess from the upper face of the molded case and alternatively, from the lower face of the molded case.
