ABSTRACT:
Unitary switch mounting and actuating apparatus, particularly suitable for use on automatic conveyer systems, comprises a case having a back wall with an aperture formed therein and two spaced side walls. A shaft is pivotally mounted between the side walls opposite the aperture in the back wall. An externally threaded nipple is welded to the back wall over the aperture therein. A radial leg is fixed on the shaft and extends through the aperture and nipple to a contact foot. A radial arm is fixed on the shaft. A torsion spring surrounds the shaft and resiliently urges the leg and arm into the unactuated position. A platform welded to the case supports a switch with its actuation element aligned with the radial arm. Movement of the leg from its unactuated position moves the shaft angularly and swings the radial arm to depress the actuation element of the switch to change the condition of the switch. The apparatus is mounted on a conveyer by locating the nipple in a hole of the conveyer rail and tightening a nut on its threaded portion against the conveyer. This locates the contact foot on the radial leg in the path of items traveling on the conveyer so that the apparatus is actuated when an item moves the contact foot and radial leg.
