ABSTRACT:
An adjustable mounting assembly for a limit switch is disclosed which includes a stationary H-shaped base plate attachable to a machine table, a movable plate slidably mounted on the base plate upon which a limit switch is carried, an adjusting screw interconnecting the plates, and locking screws which are inserted through elongated slots in one of the plates into threaded holes in the other plate which lie along the centerline of the slots for locking the plates together once the desired position of the switch has been obtained. The assembly is adaptable for moving the switch along its longitudinal centerline, along a line parallel with the table and perpendicular to its longitudinal centerline, or in a direction normal to the table and perpendicular to its longitudinal centerline. The movable plate contains at least one tab which projects into one of two outwardly opening slots in the base plate which are separated by a cross member. The adjusting screw extends through an untapped hole in one of the tabs and is threadably inserted into a tapped passageway which extends through the cross member. An E-ring contained in a circular groove on an untapped neck portion of the screw holds the screw head closely against the tab through which the screw is inserted so that rotation of the screw and its movement through the passageway produces corresponding movement of the movable plate.
