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.

A ball bearing plunger actuator for a limit switch is provided with an insert between the ball bearing and the actuator. The insert is disposed into an opening in the distal end of the actuator before insertion of the sphere. After swaging the sphere is captivated within the opening of the actuator with the low friction insert disposed at the bottom of the opening between the sphere and the actuator. In a preferred embodiment of the present invention, the low friction insert is made of a fluorocarbon, such as TFE. Several embodiments of the present invention incorporate inserts which are differently shaped to provide certain advantages in particular adaptations. Two of the embodiments utilized either a generally cylindrical insert with a conical concave part of the insert shaped at one end to receive the ball bearing or, alternatively, a generally flat circular disc of fluorocarbon material which conforms to the bottom of the opening and is inserted into the opening prior to insertion of the sphere.
