ABSTRACT:
A pushbutton linear operator for use with an electrical contact block includes a base portion, which is preferably rectangular, and a hollow cylindrical extension having external threads on an end opposite the base portion. A pushbutton having a flush, extended or mushroom cap connected to a stem is disposed in the extension. A base plate, also preferably rectangular, is integrally formed with the stem and fits within the base portion of the operator. A clamp ring is threaded to the extension to retain the cap, stem and plate in the extension and base portion of the operator. The operator is adapted to be connected to a biased contact block or biasing means may be included in the extension to "load" the pushbutton operator against a gasket for "Oil-Tite" sealing.
