Abstract
A switching device includes a housing having an exterior surface with at least one opening in the surface. An inner edge of the opening is for receiving and securing solid bodies. At least a portion of the inner edge of the opening includes an integral weld tab which is raised above a level of the exterior surface. A sensing body includes a sensing structure operable to sense at least one condition. The sensing body has an outer surface that is disposed partially within the housing and secured to the edge of the opening by the weld tab, wherein the weld tab provides weld material physically bonding the outer surface of the sensing body to the housing.
